Given an int variable n that has been initialized to a positive value and, in addition, int variables k and total that have already been declared, use a for loop to compute the sum of the cubes of the first n whole numbers, and store this value in total. Thus if n equals 4, your code should put 1*1*1 + 2*2*2 + 3*3*3 + 4*4*4 into total. Use no variables other than n, k, and total.
Explanation & answer:
We do not know which language you are using, so a pseudocode will be given, it will be similar to java or C/C++. For other languages, you can adapt to the syntax of the target language.
int n=5;
//
total = 0 // initialize variable to store total value, already declaired.
// k will be used as a dummy variable, already declared
for (k=1; k<=n; k++){
total+=k*k*k; // k*k*k works for almost all languages. adapt as needed
}
print(n, total)
_______________, such as BASIC, Python, Java, Prolog, and C , make the programming process easier by replacing unintelligible strings of 1s and 0s or cryptic assembly commands with understandable commands, such as PRINT and WRITE.
Answer:
High level Languages
Explanation:
High level languages are made so that the byte code, Assembly code that computers can understand should be converted into a higher level human understandable languages such as Python,C++. Also, remember that the compilers of these languages such as Visual studio ultimately converts the high level code into low level code ( Assembly code ) that computers can understand.
Write an if/else statement that adds 1 to the variable minors if the variable age is less than 18, adds 1 to the variable adults if age is 18 through 64, and adds 1 to the variable seniors if age is 65 or older.
Answer:
Explanation:
data is a statement like
data 10,20, 30 , 40 , 50, 60 , 70, 80
\\the numbers represent ages.
For x := 1 to end of data do a[x]:=read(data)
\\ This is a comment. You could do this much easier if you just use three if statements rather than the if then else.
minor:=0;adult:=0;senior:=0;
while a[x] <> 0 do begin
age:= a[x]
if age < 19 then minor:=minor + 1;
If age > 18 then if age < 65 the adult:=adult + 1;
if age > 64 then senior := senior + 1;
end;
I have not declared the variables anywhere. That depends on what language you are using. The key step you want are the three if statements. How you find out what's in them is another matter.
Consider this data sequence: "3 11 5 5 5 2 4 6 6 7 3 -8". Any value that is the same as the immediately preceding value is considered a consecutive duplicate. In this example, there are three such consecutive duplicates: the 2nd and 3rd 5s and the second 6. Note that the last 3 is not a consecutive duplicate because it was preceded by a 7. Write some code that uses a loop to read such a sequence of non-negative integers , terminated by a negative number. When the code finishes executing, the number of consecutive duplicates encountered is printed. In this case, 3 would be printed. Assume the availability of a variable, stdin, that references a Scanner object associated with standard input. That is, stdin = new Scanner(System.in); is given.
// Variable to keep track of array size
int length = 0;
// Array itself
int array[] = {};
// while loop will take input in the array until a negative number is entered
while(input>=0){
stdin = new Scanner(System.in);
array[length] = stdin;
length +=1;
}
// int variable to terminate while loop
int i =0;
// keep track of index of output array
int y =0;
while(arr[i] != length){
// making output array
int output[]={}; bool flag;
// put the element in out put array considering if it the desired one
output[y] = array [i];
// Now check if it was the desired?
for(int z=1;z<=length;z++){
if(array[i+z]!=output[y]){
flag = true;
}
else
{
output[y]=0;
y+=1;
}
if(array[i+z+1]=output[y] && flag == true){
output[y] = array[i];
y+=1;
}
}
//output the array
for(int o=0;o<y;o++)
System.out.println(output[o];
To solve this problem, use a loop to read the sequence of non-negative integers terminated by a negative number. Compare each number with the previous number and increment a counter if they are the same. Print the value of the counter representing the number of consecutive duplicates encountered.
Explanation:To solve this problem, we can use a loop to read the sequence of non-negative integers terminated by a negative number. We can keep track of the consecutive duplicates encountered by comparing each number with the previous number. If they are the same, we increment a counter. If they are different, we continue with the next number. Finally, we print the value of the counter, which represents the number of consecutive duplicates encountered.

An administrator has initiated the process of deploying changes from a sandbox to the production environment using the Force IDE. What information must be supplied to the IDE during this process? Choose 3 answers: - The environment into which the changes was deployed - The related change set connection Information - The username and password of the destination environment - The data of the fields which are being deployed - The metadata components that need to be deployed
Option A because the environment should be selected for which the changes are to be applied. In a time Force IDE has many project environments for example maybe a java project and C++ project would be there on sandbox, so the environment selection is important.
Option B because the related changed sets should be specified so that other developers that have access to the project can see the changes being made.
Option D The data fields that are needed to be deployed should also be provided so that the updated version can be seen by other developers.
Rejected Options :
Option C user name and password has nothing to do with the production environment because if the user has it only then it can come and make changes.

Compose a C++ function named getSpeed that uses a reference parameter variable named speed to accept an integer argument. The function should prompt the user to enter a number in the range of 20 through 70. The value entered by the user should be validated and stored in the parameter variable. Set the parameter variable to zero if the user enters a number outside the range of 20 through 70. void getSpeed (int &speed) { Cout << “Enter a number in the range between 20 and 70” << endl; Cin>>speed; If ( speed <=20 || speed >= 70) Speed = 0; }
// Making the function
void getSpeed(int &speed){
// initialize the variable to take input
int input =0;
cout << " Enter the Number in range of 20 through 70 : "<<;
cin>>input;
// validate the input
if(input>=20 && input<=70)
speed = input;
else
speed = 0;

Write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive. After the loop terminates, it prints out, on a line by itself and separated by spaces, the sum of all the even integers read, the sum of all the odd integers read, a count of the number of even integers read, and a count of the number of odd integers read, all separated by at least one space. Declare any variables that are needed.
Answer:
The loop for the given scenario is shown.
while( num >= 0 )
{
if( num%2 == 0 )
{
sum_even = sum_even + num;
count_even = count_even + 1;
}
else
{
sum_odd = sum_odd + num;
count_odd = count_odd + 1;
}
cout << "Enter a positive number." << endl;
cin >> num;
}
Explanation:
The program uses three variables to hold the user input, sum and count of even numbers and odd numbers.
int sum_even, sum_odd, count_even, count_odd, num;
The sum variables are initialized.
sum_even = 0;
sum_odd = 0;
count_even = 0;
count_odd = 0;
Only positive input from the user needs to be considered as per the question, hence, while loop is used.
This loop will execute only if the user inputs valid number. Upon entering the negative number which is less than 0, the loop terminates.
Following this, the sum and count of even numbers is displayed followed by the sum of negative numbers.
cout << sum_even << " " << sum_odd << " " << count_even << " " << count_odd << endl;
The c++ program for the given problem statement is as follows.
#include <iostream>
using namespace std;
int main()
{
// variables declared for sum and input
int sum_even, sum_odd, count_even, count_odd, num;
// sum initialized to 0
sum_even = 0;
sum_odd = 0;
count_even = 0;
count_odd = 0;
cout << "This program calculates the sum and count of even and odd numbers which are positive. This program will end on invalid input." << endl;
cout << "Enter a positive number." << endl;
cin >> num;
// loop will terminate if the user inputs negative number
while( num >= 0 )
{
// for even numbers, input is added to sum_even else sum_odd
if( num%2 == 0 )
{
sum_even = sum_even + num;
count_even = count_even + 1;
}
else
{
sum_odd = sum_odd + num;
count_odd = count_odd + 1;
}
cout << "Enter a positive number." << endl;
cin >> num;
}
cout << sum_even << " " << sum_odd << " " << count_even << " " << count_odd << endl;
return 0;
}
OUTPUT
This program calculates the sum of even and odd numbers which are positive. This program will end on invalid input.
Enter a positive number.
23
Enter a positive number.
56
Enter a positive number.
78
Enter a positive number.
91
Enter a positive number.

To accomplish the student's task, we can use a while loop to continuously read integers and accumulate sums/counters for even and odd numbers, terminating the loop when a non-positive integer is encountered. The resulting sums and counts are then printed out.
To write a loop that reads positive integers from standard input and terminates when a non-positive integer is read, we can use a while loop in a programming language such as Python. Below is an example of how this could be achieved:
sum_even = 0
sum_odd = 0
count_even = 0
count_odd = 0
while True:
number = int(input("Enter a positive integer (or a non-positive integer to quit): "))
if number \<= 0:
break
if number % 2 == 0:
sum_even += number
count_even += 1
else:
sum_odd += number
count_odd += 1
print(sum_even, sum_odd, count_even, count_odd)
In this code, we initialize the variables sum_even and sum_odd to keep track of the total sum of even and odd numbers respectively. Similarly, count_even and count_odd are used to keep a count of even and odd numbers. The while loop continues to prompt the user for a number and checks if it is even or odd, updating the sums and counts accordingly. The loop breaks when a non-positive number is entered, after which it prints the sum of even numbers, the sum of odd numbers, the count of even numbers, and the count of odd numbers, all separated by spaces.
Write a method named lastFirst that accepts a string as its parameter representing a person's first and last name. The method should return the person's last name followed by the first initial and a period. For example, the call lastFirst("Marla Singer") should return "Singer, M." . You may assume that the string passed consists of exactly two words separated by a single space.
I'm going to assume this is Java, because you said "method" meaning it will be some sort of object oriented language, and Java's really common. Here would be the full program, but you can just take the method out isolated if you need it.
package lastname;
public class LastName {
public static void main(String[] args) {
// Example usage:
String name = LastName.lastName("Garrett Acord");
System.out.println(name);
// Output: Acord G.
}
public static String lastName(String fullName)
{
String[] splitName = fullName.split(" ");
return String.format("%s %s.", splitName[1], splitName[0].substring(0,1) );
}
}
Final answer:
The method 'lastFirst' takes a full name as input and returns a string with the last name, followed by the first initial and a period. This can be implemented in a programming language like Java, and calling 'lastFirst("Marla Singer")' will return 'Singer, M.'.
Explanation:
The method lastFirst is designed to take a string input representing a person's first and last name, and return a formatted string with the last name followed by a comma, a space, the first initial of the first name, and a period. Here is how you could implement the method in Java:
public String lastFirst(String fullName) {
int spaceIndex = fullName.indexOf(" ");
String firstName = fullName.substring(0, spaceIndex);
String lastName = fullName.substring(spaceIndex + 1);
return lastName + ", " + firstName.charAt(0) + ".";
}
For example, when you call lastFirst("Marla Singer"), the method will return "Singer, M."

Assume that two int constants,FIRST_YEAR and LAST_YEAR have already been declared and initialized with year values (like 2009, 2014), along with a double variable oil that has been initialized with the number of barrels of oil consumed in Canada in the year given by FIRST_YEAR. Write some code that uses a while statement to print on a line by itself, each of the years from FIRST_YEAR to LAST_YEAR inclusive. On each line, after the year, separated by a colon and a space, print the new value amount of oil, taking into account that each year the oil consumed increases by 20%.
// While loop
while(FIRST_YEAR < LAST_YEAR)
{
cour<<"Year : " << First_YEAR << " Oil consumed is : " << oil <<"."<<endl;
FIRST_YEAR+=1;
// calculate the 20% increase
oil = oil + (oil *.20)
}

Which major NIMS Component describes systems and methods that help to ensure that incident personnel and other decision makers have the means and information they need to make and communicate decisions?
Answer:
1.Communication Management
2.Information Management
Explanation:
NIMS has introduced COMMUNICATION management system that determines if the decision makers has the ways to communicate decisions. It has standards that defines the ways that can be used by the personnel to communicate the decisions in a better and efficient manner.
NIMS has also a system which is primarily introduced to check the the personnel has the information to make and communicate decisions called Information management. Again, it also has the templates that defines that how information should be spread considering the confidentiality of the information.
Communications and Information Management is the major NIMS (National Incident Management System) Component that describes systems and methods ensuring that incident personnel and other decision-makers have the means.
Who: Incident personnel and decision-makers involved in managing an emergency or disaster situation.
What: Communications and Information Management deals with the systems, tools, and methodologies used to gather, organize, manage, and disseminate information effectively. This ensures that all participants have access to the accurate and timely information required to make informed decisions and coordinate efforts.
When: Effective communication and information management need to be in place at every stage of an incident, from the initial response through to recovery. This helps in maintaining a coordinated and efficient response effort throughout the incident.
Where: These systems and methods are applied wherever an incident or emergency situation occurs. This can include local, state, and national levels, and sometimes even international scenarios, depending on the nature and scope of the incident.
Why: The primary purpose of this component is to ensure seamless information flow among incident personnel, helping to support decision-making processes and enhance overall incident management. This ultimately leads to a more efficient and effective response and recovery effort.
How: Communications and Information Management involves using various tools and technologies, such as incident command systems, public information systems, alert and warning systems, and interoperable communication systems. These tools help ensure that critical information is shared accurately and timely among all relevant stakeholders.

Pete is designing a web page for a clothing company. He wants to show the different types of clothing lines available through a video. He wishes to use Adobe Flash Player to play the videos on the website.Pete wants to set the playback quality parameter of the movie where the display quality of the video is favored over the playback speed. Which of the following values of the quality parameter must he apply to accomplish this?falsetruelowhigh
Final answer:
Pete should set the quality parameter of the video to 'high' in Adobe Flash Player to prioritize display quality over playback speed.
Explanation:
Pete is designing a web page and wants to use Adobe Flash Player to play videos with a focus on display quality over playback speed. To achieve this, Pete should set the quality parameter of the video to 'high'. When the quality parameter is set to high, it ensures that the video will be displayed with the best quality possible, even if this means that the video might buffer or play back with less speed on slower internet connections or less capable devices. This setting prioritizes the visual experience for users who want to see the clothing lines with the highest image clarity and detail.

Write three separate code which would use a while loop, for loop and do ..while loop to output integers 200 down to 50 with their squares listed besides the integers which increments by steps of -10
Answer:
The c++ program using for loop is given below.
#include <iostream>
using namespace std;
int main() {
int sq, i;
cout<<"Integer"<<"\t"<<"Square"<<endl;
for(i=200;i>=50;i=i-10)
{
cout<<i<<"\t"<<"\t";
sq=i*i;
cout<<sq<<endl;
}
return 0;
}
The c++ program using do-while loop is given below.
#include <iostream>
using namespace std;
int main() {
int sq, i=200;
cout<<"Integer"<<"\t"<<"Square"<<endl;
do
{
cout<<i<<"\t"<<"\t";
sq=i*i;
cout<<sq<<endl;
i=i-10;
}while(i>=50);
return 0;
}
The c++ program using while loop is given below.
#include <iostream>
using namespace std;
int main() {
int sq, i=200;
cout<<"Integer"<<"\t"<<"Square"<<endl;
while(i>=50)
{
cout<<i<<"\t"<<"\t";
sq=i*i;
cout<<sq<<endl;
i=i-10;
}
return 0;
}
OUTPUT
Integer Square
200 40000
190 36100
180 32400
170 28900
160 25600
150 22500
140 19600
130 16900
120 14400
110 12100
100 10000
90 8100
80 6400
70 4900
60 3600
50 2500
Explanation:
The integer variables sq and i are declared to hold the square and the integer respectively. The square of an integer is also a square hence, it is also declared as integer and not float.
The variable i is initialized to 200 as required by the question. All the three loops continue till value of i reaches 50. Once, the value goes below 50, loop is discontinued.
In for loop initialization, condition and decrement, all are done simultaneously.
for(i=200;i>=50;i=i-10)
In do-while and while loops, variable declaration and initialization are done simultaneously. The condition and decrement logic is contained within the loop.
This loop executes once irrespective whether the condition is satisfied or not. From the second execution onwards, the condition is taken into account.
do
{
cout<<i<<"\t"<<"\t";
sq=i*i;
cout<<sq<<endl;
i=i-10;
}while(i>=50);
The while loop is similar to do-while loop except that the while loop executes only if the condition is satisfied.
The output for all the three loops is the same hence, output is shown only once.
Which statement is NOT CORRECT?
In a file approach to data management, the data definitions are included in each application separately.
The file approach to data management causes the same information to be stored separately for different applications.
In a file approach to data management, a change in the structure of a data file is easily handled because each application has its own data files.
In a file approach to data management, different applications could be using older and newer versions of the same data."
Option C is not correct because in file system there is problem of using same data at different place with old and new updated versions and thus change in the data on one file is not reflected on the other related files implicitly rather we will have to change the data in each file manually which is indeed not easy task. In fact that is one of the biggest drawback of file system.
Option A is correct because the files of different data has separate definitions of the topics they are about.
Option B is correct because has no reversibility and thus same data can be present on different files.
Option D is correct because because of no reversibility the files can have same records with new or old versions

To adjust the height of cells, position the pointer over one of the dividing lines between cells. When the pointer changes to the _______ shape, drag the dividing line to the correct position.
Answer:
double arrow shape
Explanation:
To adjust the height of the cells
1. We have to position the mouse pointer over one of the column line or the one of the row line.
2. As we place the pointer between the dividing lines, the cursor of the mouse pointer change from singe bold arrow to double arrow symbol.
3.Now press or click the left mouse button and drag the dividing lines of the cells to the desired position to have the required width or height of the cell.
An administrator has created a new custom object in a sandbox environment and now is ready to deploy in production. How can the administrator ensure that the field-level security that was tested and approved in the sandbox environment is maintained as part of the deployment? a) Create a change set that includes the custom object and all custom fields b) Create a change set that includes the custom object and all profiles c) Create a change set that includes the custom object, check the retain field-level security option d) Create a change set for the custom object; use Data Loader to transfer field-level security
Answer:
Option D
Explanation:
Option A is rejected because adding a custom object will cost both in memory and computation power. Consider that you have 1 million users, than there will be 1 million custom objects in the memory for checking the security which is not good.
Option B is not answer because again making a custom object will cost in memory and computation power.
Option C is not good because it also makes the custom object.
Option D is selected because change sets can be made which will not cost as much as the other options are costing. Also Data Loader can have come credentials defined in it which we can use to check if the user activities are according to the rules at each level.These days these data loader object technique is used because there will be static change sets for the class of users to check security.

return (goalsScored – otherPlayer.goalsScored);
}
}
What statement can be used to complete the compareTo()method?
A. Player otherPlayer = otherObject;
B. Object otherPlayer = otherObject;
C. Player otherPlayer = (Player) otherObject;
D. Object otherPlayer = (Player) otherObject;
Answer:
OPtion A
Explanation:
As otherObject is coming as a parameter to the function, there must be another object of type player that it should be assigned to so that we can compare its field.
IN Option B there is syntax error that Object class is not defined, if defined also the comparison will not work because the comparison can be done for same type objects.
In Option C the right hand size is syntax error because there is no definition of it in Java.
In Option C also there is syntax error and it its right hand size is not defined.
