Something within a while loop must eventually cause the condition to become false, or a(n) __________ results.
1. null value
2. infinite loop
3. unexpected exit
4. compiler error
5. None of these
Answer: Infinite loop
Explanation:
A while loop terminates when the condition within the loop becomes false else the it will continue to loop for ever and thereby lead to memory overflow.
example : while(i<10)
{ print("hello");
}
here if value of i <10 then it will print hello, but if there is no condition it will lead to an infinite loop. example : while();
You may declare an unlimited number of variables in a statement as long as the variables are ____.
a.
initialized to the same value
b.
the same data type
c.
properly commented
d.
floating point numbers
Answer:
b. the same data type
Explanation:
Any number of variables can be declared in a statement as long as the variables have the same data type. For example:
1) int a,b,c,d,e;
Here each of the declared variables a,b,c,d,e have the type int.
2) char p,q,r,s,t,u,v,w;
In this case variables p to w all have the type char.

Answer:
if workExperience>=2 or hasCollegeDegree==True:
print("Application accepted")
Explanation:
In the first line of code, we wrote an if statement that allows us to print a message if and only if the int variable workExperience is greater than 2 or the bool variable workExperience is TrueIn the second line of code, we print the message Application accepted if the if-statement evaluated to TrueNote: This code was written in python but you can extend the same concept to any programing language using if, comparison operation, boolean operators and print function.
What width would you choose for the pdf?
Answer:
I would go for a width of 8.27 inches
Explanation:
The width of your PDF file depends on the project you are working on as well as your use case. Putting that aside, you are always better off making the dimensions of your PDF the same as the dimensions of A4 printing paper, which is 8.27 inches or 21 centimeters (2480 pixels). This is because A4 is the most common printing paper used and will make organization and printing less of a hassle.

Write an application that can hold five integers in an array. Display the integers from first to last, and then display the integers from last to first.
Answer:
Create an integer array which holds five integers
Explanation:
I have written a simple program using c# as a programming language.
Here's the program:
using System;
public class Test
{
public static void Main()
{
int[] numbers = new int[5];
Console.WriteLine("enter 5 numbers");
for (int i=0; i<=4; i++)
{
numbers[i]= Convert.ToInt32(Console.ReadLine());
}
foreach(int k in numbers)
{
Console.WriteLine(k+ "\n");
}
Console.WriteLine("----------------------------");
Console.WriteLine("In reverse");
for(int j=4; j>=0; j--)
{
Console.WriteLine(numbers[j] + "\n");
}
Console.ReadLine();
}
}
Explanation of Program:
I have created an array named "numbers" and assigned 5 as it's fixed size.
I prompted the user to enter numbers up to 5. I read those input numbers using Console.ReadLine() and converted to integers as return type of Console.ReadLine() is string. I have stored all inputs from user into an array while reading as below:
numbers[i]= Convert.ToInt32(Console.ReadLine());
Next step is to print them. We can do it easily using foreach loop where it pulls out elements from an array until it reaches end of an array and print them on console.
If I need to print them from first to last, the condition is,
for (int i=0; i<=4; i++)
as it needs to start from first element
If I need to print them from last to first, the condition is,
or(int j=4; j>=0; j--)
as it needs to start from last element
The application that can hold five integers in an array and display the integer from first to last and last to first is as follows;
integers = [15, 17, 8, 10, 6]
print(integers)
x = integers[::-1]
print(x)
Code explanation:The code is written in python.
The first line of code, we declared a variable named integers. This integers variables holds the 5 integers.The second line of code, we print the the integers from first to last.The next line of code, we reversed the array from last to first and stores it in the variable x. Then, we print the x variable to get the code from last to first.learn more on array here:https://brainly.com/question/19587167

) Consider the array called myArray declared below that contains and negative integers. Write number of positive integers in the array. That is, your loop display the message "Number of positive integers is 5" a loop statement to count and display the should (4 points) int myArray[]卟1,3,-9,9,33,-4,-5, 100,4,-23); Note: The loop should always work without modification even if the values in th array are changed
Answer:
#include <iostream>
using namespace std;
int main()
{
int arr[]={3,-9,9,33,-4,-5, 100,4,-23};
int pos;
int n=sizeof(arr)/sizeof(arr[0]);
for(int i=0;i<n;i++){
if(arr[i]>=0){
pos++;
}
}
cout<<"Number of positive integers is "<<pos<<endl;
return 0;
}
Explanation:
create the main function in the c++ programming and declare the array with the element. Then, store the size of array by using the formula:
int n=sizeof(arr)/sizeof(arr[0]);
after that, take a for loop for traversing the array and then check condition for positive element using if statement,
condition is array element greater than or equal to zero.
if condition true then increment the count by 1.
this process happen until the condition true
and finally print the count.
Generally, what is the term for storage locations in a processor?
Answer: Registers
Explanation:
Registers are small storage locations identified by different types of registers. The function of the register is to provide data for immediate processing to the CPU. These registers hold data temporarily and provide easy access of data to the processor.
. A register in a computer has a of bits. How many unique combinations can be stored in the register?
Answer:
The number of unique combinations stored in the register totally dependent upon the number of bits the register can hold.
Explanation:
Suppose if the register is 2-bit.Then it can have (2²) 4 unique combinations of the bits and those combinations are 00,01,10,11.For a 3 bit register there are (2³) or 8 unique combinations those are 000,001,010,011,100,101,110,111.So for a n-bit register there can be 2ⁿ unique combinations there.

Write a C++ programme that asks the user to enter his age in days.Calculate then his age in:
Years – Months –Days
1 year = 365 days
1 year = 12 months
1 month = 30 days
C++ program that asks the user to enter his age in days
#include <iostream>
using namespace std;
void Findage() //Defining function
{
int a=0,d=0, m=0, y=0, r=0;
cout<<"Enter Age in Days= "; //Taking input
cin>>a;
if(a>365) //If age is greater than 365
{
y=(a)/365;
r=a%365;
if(r>30)
{
m=r/30;
d=r%30;
}
else
{
d=r%30;
}
}
else //if the age is less than 365
{
if(a>30)
{
m=(a)/30;
d=a%30;
}
else
{
d=a;
}
}if(a==365) //Printing output
{ cout<<"Your Age in Calender"<<endl;
cout<<"Year = 1"<<endl;
}
else
{
cout<<"Your Age in Calender"<<endl;
cout<<"Years= "<<y<<" Month="<<m<<" Days= "<<d<<endl;
}
}
int main()
{
Findage(); //Calling function
return 0;
}
Output
Enter Age in Days= 3697
Your Age in Calender
Years= 10 Month=1 Days= 17
A C++ program can be written to calculate a user's age in years, months, and days by dividing the total number of days provided by the user by 365 to find years and then dividing the remainder by 30 to calculate months, with the final remainder indicating the days.
A C++ program that calculates a user's age in years, months, and days from the age in days can be composed using simple arithmetic operations. Given that 1 year is 365 days, 1 year is 12 months, and 1 month is 30 days, the following process can be followed:
Ask the user for their age in days.
Use the remainder of the previous division to calculate the number of months by dividing by 30.
The remainder of the last division will give the number of days.
The resulting calculations will give the user's age in years, months, and days.

You can tell that the equals() method takes a ____ argument because parentheses are used in the method call.
a.
Boolean
b.
Double
c.
String
d.
Null
Answer:
c. String
Explanation:
The equals method in java String class takes an object reference as a parameter. We can compare two Strings with the help of equals method of the String class. The equals() method of the java String class compares the given strings based on the content of the string.
Use of the String equals method:-
if (stringOne> stringTwo) it will return a positive value.
if both of the strings are equal lexicographically means
(stringOne == stringTwo) it will return 0.
if (stringOne < stringTwo) it will return a negative value.
Which of the following Boolean exxpressions tests to see if x is between 2 and 15 (including 2 and 15)? A. (x <15 || x> 2) B. (2 2) && (x<= 15) D. (22)
Answer:
A. (x < 15 || x > 2)
Explanation:
The operator '||' is used for OR operation. it is used in between the conditions and give the result as Boolean (TRUE or FALSE).
There are four possible result:
First condition TRUE, second condition TRUE then result will be TRUE.
First condition TRUE, second condition FALSE then result will be TRUE.
First condition FALSE, second condition TRUE then result will be TRUE.
First condition FALSE, second condition FALSE then result will be FALSE.
In the question:
Option A: (x < 15 || x > 2)
x will be in between the 2 and 15, if it less than 15 and greater than 2. So, the expression follow the condition.
Option B: (2 2) && (x<=15)
it not the correct way to write the condition, (2 2) is not allowed.
Option D: (22)
it also not true. it show the value 22.
Therefore, the correct option is A.
Cash cows are always in
a. Introductory industry
b. Growing industry
c. Mature industry
d. Declining industry
Answer:
The correct answer is C. Cash cows are always in mature industry.
Explanation:
A cash cow is a company, business area or product that generates a large free cash flow over time. Cash flow depends on the profitability of the company or product, that is, revenues are greater than costs, but also because the surplus is not tied up in the business in the form of working capital.
The cash flow in a company can be used to pay off debt but also as a dividend to owners. An individual product that constitutes a cash cow can help to finance other activities in the company or group.
How many characters does the "short text" have?
Answer:
Total number of characters in "short text" is 10.
Total number of distinct characters is 8.
Explanation:
List of characters in "short text":
s,h,o,r,t, ,t,e,x,t - 10
Set of distinct characters is:
s,h,o,r,t, ,e,x - 8
The length can be determined programmatically in Java using String.length() api.To determine distinct characters, individual characters can be added to a Set and then the set size can be computed.
Programming: Write a recursive function to_number that forms the integer sum of all digit characters in a string. For example, the result of to_number("3ac4") would be 7. Hint: If next is a digit character ('0' through '9'), function is_digit(next) in header will return true.
yes
Explanation:
isn't really noted but if the sequence is in the given order the ("3at4") could be expressed in a ('0' to '9' )format

What are the two categories of problems that we can simply convert
to parallel code?
Which algorithm makes the most efficient use ofmemory?
Answer:
Best-fit Algorithm
Explanation:
Best-fit: Allocating the smallest memory location that is greater than or equal to the size of process.
Example
Let these are the memory locations-210kb,310kb,260kb,610kb
and size of processes-160kb,450kb,250kb,300kb
For the first-fit,
We allocate 160 kb to the 210kb memory location
Then, we allocate 450 kb to the 610kb because others don't have the size.
Then,we allocate 250kb to the 310 kb.
300 kb will stop,as no memory locations can execute.
For the Best-fit,
We allocate 160 kb to the 210kb memory location
Then,we allocate 450kb to the 610kb.
Then,we allocate 250kb to the 260kb not 310kb according to best-fit.
Then we allocate 300kb to the 310kb.
For the worst fit,
We allocate 160 kb to the 610kb memory location according to the worst-fit algorithm.
Then,we can't allocate 450kb to any memory location.
Then,we allocate 250kb to the 310kb .
We can' allocate 300kb in 260kb memory location.
As we can see from this example that in First-fit algorithm 300kb process will stop as no memory location is there.
In worst-fit algorithm ,We can't allocate 450kb,300kb to any memory locations.
In Best-fit algorithm,we can allocate the process to each location,so this algorithm is using memory in a efficient way.
