Answer:
False
Explanation:
The good example of pivoting is NOT changing the dimensions along the axis.
You have the templates of 2 classes, Person and Program. The Person class has 4 attributes, name, age, major and gpa. There is a constructor for the class that is used to make Person objects. There are setter/mutator methods and getter/accessor methods for those attributes. There is also a printInfo() method that prints out information about the person. The Program class has a main method that has 5 Person objects person1 to person5 declared and initialized. The main method within the class also has a Scanner object that is used to take input for a person number and a newGPA. Your task is as follows:
a. Based on the input of personSelect select the appropriate person and change their GPA to the newGPA input and then print out their information. For instance if the user types in 1 then select person 1 and print out their information using the printInfo method. Do it for all possible inputs from 1 to 5.
b. If however the input is not 1 to 5 then inform the user they have to have to type in an appropriate person number
Person.java
public class Person {
String name;
int age;
double gpa;
String major;
public Person(String aName, int aAge, String aMajor, double aGpa)
{
name = aName;
age = aAge;
gpa = aGpa;
major = aMajor;
}
/**
* @return the name
*/
public String getName() {
return name;
}
/**
* @param name the name to set
*/
public void setName(String pname) {
name = pname;
}
/**
* @return the age
*/
public int getAge() {
return age;
}
/**
* @param age the age to set
*/
public void setAge(int page) {
age = page;
}
/**
* @return the gpa
*/
public double getGpa() {
return gpa;
}
/**
* @param gpa the gpa to set
*/
public void setGpa(double pgpa) {
gpa = pgpa;
}
/**
* @return the major
*/
public String getMajor() {
return major;
}
/**
* @param major the major to set
*/
public void setMajor(String pmajor) {
major = pmajor;
}
public void printInfo()
{
System.out.println("#########################");
System.out.println("Business College ");
System.out.println("Name: " + name);
System.out.println("Major: " + major);
System.out.println("GPA: " + gpa);
System.out.println("#########################");
}
}
Program.java--------------------------------------------------------------------------------
import java.util.Scanner;
public class Program {
public static void main(String[] args) {
//Declare person objects here
Person person1 = new Person("Dewars",40 , "MIS", 3.9);
Person person2 = new Person("Budweiser",23 , "MIS", 3.2);
Person person3 = new Person("Appletons",25 , "MIS", 3.0);
Person person4 = new Person("Beam",20 , "Finance", 3.7);
Person person5 = new Person("Daniels",19 , "Accounting", 2.9);
Scanner scan = new Scanner(System.in);
System.out.println("Type in a person number whose gpa you would like to change > ");
int personSelect = scan.nextInt();
System.out.println("Type in the gpa you would like the person's to be > ");
double newGPA = scan.nextDouble();
/*
* CODE HERE
*/
}
}
Answer:
Hi, I'm going to put the code answer here and you put in the corresponding line to not copy all the code in the answer.
replace the following line or adjust to the following code
/*
* CODE HERE
while(personSelect <= 0 || personSelect > 5) {
System.out.println("Wrong number, try to input the number in range 1 to 5" );
personSelect = scan.nextInt();
}
if(personSelect == 1){
person1.setGpa(newGPA);
printInfo()
}
else if(personSelect == 2){
person2.setGpa(newGPA);
printInfo()
}
else if(personSelect == 3){
person3.setGpa(newGPA);
printInfo()
}
else if(personSelect == 4){
person4.setGpa(newGPA);
printInfo()
}
else {
person5.setGpa(newGPA);
printInfo()
}
*/
Explanation:
According to the description of code, we have to add some lines to resolve the questions.
a):
In base on the input, we have to modify the attribute GPA with the method setGpa depending on the person chosing. We call the person chosen before and also call the method setGpa( ) and pass as parameter the GPA value obtained in tha last input
b)
In this case we have to create a loop for iterate the times that is necesary to get a value of person that is permit in range 1 to 5, and hence that we create and individual if condition to assign the GPA to the person chosen.
I hope it's help you.
Write a C++ program which contains a user-defined functionhaving name isSortedthat returnstrue if the array is sorted,and returns false if thearray is not sorted In main functionask the user to enter 10 integers and store them in array and thencall the function by passing this array. If array is sorted thendisplay message "Array is Sorted" otherwise displaymessage "Array is not Sorted"
Answer:
#include<iostream>
using namespace std;
//create the function
bool isSorted(int arrays[]){
int Array_size=10;//store the size
//check for condition if array is size 1 or zero
if(Array_size==1 || Array_size==0){
return true;
}
//traversing the array and check for sort
for(int i=1;i<Array_size;i++){
if(arrays[i-1]>arrays[i]){
return false;
}
}
return true;
}
//main function
int main(){
//initialization
int arrays[10];
cout<<"Enter the 10 numbers: "<<endl;
//for storing the value in array
for(int i=0;i<10;i++){
cin>>arrays[i];
}
//call the function and check is true or not and display message
if(isSorted(arrays)){
cout<<"Array is Sorted"<<endl;
}else{
cout<<"Array is not Sorted"<<endl;
}
return 0;
}
Explanation:
Include the library for using the input/output instruction.
create the function 'isSorted' with one parameter arrays and return type id bool. It means the function returns the true or false.
then, declare the variable and check the condition using the if-else statement. if the array size is zero or one, it means the array is sorted. So, the function returns true. otherwise, the program executes the next statement.
After that, take a for loop and traversing the array, an if-else statement is used for checking the previous element is greater than the next element, if condition true, the function returns the false.
after the loop checked all the element and the loop does not return false. It means the array is sorted and the function returns true.
create the main function and declare the array with size 10.
print the message on the screen and then store the element in the array.
we take a for loop and it runs 10 times. so, the user enters the number for every cycle of loop and store in the array.
after that, calling the function with an if-else statement, as we know the function returns the Boolean. So, if the function returns true then if statement executes and print message otherwise else statement executes and prints the appropriate message.
what are the purpose of each in c++?
if statements?
switch statements?
multiway if?
nested loops?
rand?
srand?
seed?
If statements- This statement is used to check the condition.
if(condition)
{
statement
}
If the condition is true,then statement will run,else not.
Switch statement-This statement is used for long conditions.It is a substitute for if,else conditions
switch(a)
{
case1: statement 1//if a=1
break;
case2: statement 2 //if a=2
break;
.....
default:statement//if a is not equal to any of the cases.
Multiway if-In this statement ,if elseif and else were there.
if(condition1)
{
statement 1
}
elseif(condition2)
{
statement 2
}
..............
else
{
statement n
}
Nested loops-This statements are used when we use if-else conditions in other if,else conditions.
if(condition 1)
{
if(condition 2)
{
if (condition 3)
{
statement 3
}
else
{
statement 4
}
}

seed()-It is a method for initializing the same random series,it is passed in srand().
Suppose a restaurant sells soft tacos, crunchy tacos, hamburgers with cheese, hamburgers without cheese, and fried chicken. Your coverage criterion says to taste each type of dish, One option for all dishes is to serve them with very hot sriracha sauce; so much that it completely covers the taste of the rest of the ingredients. If your boss told you to taste the items without the sriracha sauce, what kind of testing problem would that avoid?
a) redundancy
b) coverage
c) controllability
___ is an example of a calling statement.
A) float roi(int, double);
B) printf("%f", roi(3, amt));
C) float roi( int yrs, double rate);
D) float roi( int yrs, double rate)
Answer:
printf("%f", roi(3, amt));
Explanation:
To call the function, we have to put the function name without return type and if the function have parameter then we have to pass the parameter without data type as well.
Let discuss the options:
Option A: float roi(int, double);
it is not a calling, it is used to declare the function. In calling, return type of the function like float and data type of the parameter does not pass like int, double.
Option B: printf("%f", roi(3, amt));
print is used to display the result, inside the print it call the function. It is correct way to call the function.
Option C: float roi( int yrs, double rate);
it is not a calling, it is used to declare the function. In calling, return type of the function like float and data type of the parameter does not pass like int, double.
Option D: float roi( int yrs, double rate)
Same reason as option C.
Therefore, the option B is correct option.
Compare and contrast Superscalarand VLIW processor technology
Answer:
VLIW stands for the very long instruction word and it basically works on the principle of RISC that is reduced instruction set computer. It is the combination of the multiple instructions by the compiler. It has simple hardware architecture and instruction and while designing in VLIW compiler are performed the difficult tasks.
In super scalar, it is the processor with multiple pipeline instructions, which basically allowed various instruction to be process simultaneously in each cycle. It is basically the method of parallel computing which are used in various processor.
Which element would the search element be compared to first, if abinary search were used on the list above?
4
35
44
98
Answer:
35
Explanation:
Binary search is more efficient than linear search,time complexity of binary is 0(logn) where as linear's 0(n).In binary search we search from the middle of the array,whereas in linear we start with index 0 until the last.
4
35
44
98
List contains 4 elements, for finding the middle element we will divide by 2 .
4/2=2 so at the index 2 -35 is present ,we will start checking from 35.
Organizations are struggling to reduce and right-size their information foot-print, using data governance techniques like data cleansing and de-duplication. Why is this effort necessary? Briefly explain.
The effort is necessary in making sure that the data is meaningful, correct, and timely. Many analysts are increasingly focused on quality on a per-attribute basis instead of a per-report basis. This will avoid excess control of access and instead focus on meaning. A data-driven organization that includes a comprehensive data cleanup is able to make informed choices that maximize value on strategic investments.
This means to increase a value by one..
1. decrement
2. increment
3. modulus
4. parse
5. None of these
Increment means to increase a value by one. Incremental change is change in a value by one. Hope this helps!
Write a java program that finds the sum of all even numbers between 1 and 55.
Also what modification would you do to the program if you wanted the sum of all odd numbers between 1 and 55
Answer:
For sum of even Number :
public class even{
public static void main(String []args){
int sum = 0;
for(int i=1;i<=55;i++){
if(i%2==0){
sum = sum + i;
}
}
System.out.println(sum);
}
}
Modification for sum of odd:
change the condition of if statement:
i%2==1 instead of i%2==0
Explanation:
create the main function and declare the variable with zero.
Then, take a for loop for traversing the number from 1 from 55.
Inside the for loop, if statement check the condition for even number
A number is even if number divide by 2 and give zero reminder.
so, number%2==0 it is the condition for even number.
then add the even number until condition TRUE.
and finally print the result.
Modification for sum of odd number:
A number is odd, if number divide by 2 and give one reminder.
it means, number%2==1 it is the condition for odd number.
just change the if condition with above.

Which ofthe following must NOT be adopted in preparing disappointing newsmessages?
a- Use sales-promotionmaterial whenever appropriate.
b- Consider using animplicit refusal rather than an explicitrefusal.
c- Capitalize on what youcan do for the reader rather than what you cannotdo.
d- Use negative words orphrases.
Answer: D) Use negative words or phrases.
Explanation:
Use negative words or phrases must not be adopted in preparing disappointing news messages as if news itself is a disappointing then there is no need to support that idea with no hope. So, we should always using helpful data and path of positive way as, it is the best choice.
The ____ operator is written as the exclamation point ( ! ).
a.
NOT
b.
assignment
c.
equality
d.
AND
Answer:
NOT
Explanation:
The operator '!' is called the NOT operator. it is used to invert the value of the Boolean.
if Boolean is TRUE then it make it FALSE.
if Boolean is FALSE then it make it TRUE.
For example:
!(6>0)
the expression gives the FALSE result. because the condition is TRUE 6>0
But the NOT operator make it FALSE.
What will the following code print out: int numbers [] = {99, 87, . 66, 55, 101}; for (int i = 1; i < 4; i++) cout << numbers [i] << end1;a) 99 87 66 55 101 b) 87 66 55 101 c) 87 66 55 d) Nothing.
Answer:
87 66 55
Explanation:
Array is used o store the multiple values with same data type.
the array show a decimal value .66, i assume this is enter by mistake because option has no decimal value.
The index of the array is start from zero, it means the first element store in the array at position zero.
In the for loop the variable 'i' start from 1 not zero and it goes to i<4 means i=3.
So, it access the element from 2 to 4 because the index is position of element less than 1.
Therefore, 87 66 55 print.

a.
copied
b.
used
c.
saved
d.
extended
Answer:
The correct answer is d.extended.
Explanation:
In order to have a superclass in Java, it is indispensable to extend, or inherit from, a class. It means that a subclass is created by an extended class. All the classes in Java only need one superclass from which it inherits some of its fields and methods.
Answer:
d.extended
Explanation:
The answer is d.
You usually has a top public class, for example, animals, with it's own attibutes. Then you can have other classes extending animals, for example, cats. These classes have both the attributes of the parent class, and their own attributes.
So the code goes something like this
public class Animals{
public Animals(){
\\constructor with attributes
}
\\code
}
public class Cats extends Animals{
public Cats(){
\\constructor with the extra attributes.
}
\\code
}

Input-the input should be given in proper steps to get the desired output Output-the output is usually is one or more which is derived from the input instructions.Finite instructions-it is desired that the given instruction should be in a finite number of steps.Effectiveness- it is expected that the algorithm should be in basic form and effective enough to be understood easily.The process of acquiring data for a program to use is called:
Select one:
a. data entry
b. graphical user interface
c. input
d. display
e. concatenation
Answer:
a. Data Entry
Explanation:
Great Question, it is always good to ask away and get rid of any doubts you may be having.
The process described in the question is called Data Entry and/or Data Acquisition. Data is gathered and stored in the computers memory to then be used by a specific program or function. Without this data being gathered the program or function cannot complete its task. Therefore Data Entry is extremely needed for the correct and healthy function of a program.

Where do you define parameter variables?
Answer:
In the function definition.
Explanation:
Function is the block of statement which is used to perform a special task.
when we define the function, we have call the function as well without calling function is not used.
syntax for calling:
name(argument_1,argument_1,...);
we put the argument in the calling to function.
syntax for defining:
type name(parameter_1,parameter_2,.....)
{
statement;
}
In the definition, we declare parameter for use the value of arguments pass in the calling.
Therefore, the answer is in the function definition.
What is meant by instruction pipelining in RISC processor? Whatare
'/ the problems that may accompany this technology?
Answer:
Explanation:
The instruction pipelining refers to various stages the instruction has to go through for the full execution of the instruction. Each instruction undergoes various stages in the execution, they are Instruction Fetch, Instruction Decode, Address Generator, Data Fetch, Execution and Write Back. Not every instruction may go through all the stages stated above. Pipelining exploits the parallelism in the execution of instructions (executing multiple instructions simultaneously ). Each instruction might be at different stage in the execution of program. It can be a 3-stage pipelining or 5 stage pipelining.
The implementation of Pipelining is a complex procedure.
In branch instructions, the complexity increases with the number of stages of pipeline.
Which of the following is not a standard method called as partof the JSP life cycle?
? jspInit()
? jspService()
? _jspService()
? jspDestroy()
Final answer:
The method _jspService() is not a standard part of the JSP lifecycle; it's an implementation detail by JSP containers but not to be directly used by developers.
Explanation:
The question pertains to the standard methods in the JavaServer Pages (JSP) life cycle. In JSP, there are several lifecycle methods that the JSP container (like Tomcat or Jetty) calls to manage the JSP page. These methods include jspInit() for initialization, jspService() for processing requests, and jspDestroy() for cleanup when the JSP is about to be destroyed. However, the method _jspService() is not part of the JSP life cycle and is actually an implementation detail used by some JSP containers. This method is typically generated by the JSP container during JSP to servlet conversion and should not be called directly by developers.
Create a static method called fillArray, which takes an integer array as an input parameter, along with an integer initial value. It should then fill the array with values starting from the initial value, and counting up by 1s. For example, if the data array has length 5, and if the initialValue is 3, then after execution the array should hold this sequence: 3 4 5 6 7. public static void fillArray (int[] data, int initialValue) {
Answer:
public class print{
public static void fillArray(int[] arr, int initialValue){
int n = arr.length;
for(int i=0;i<n;i++){
arr[i] = initialValue++;
}
for(int i=0;i<n;i++){
System.out.print(arr[i]+" ");
}
}
public static void main(String []args){
int[] array = new int[5];
int initialValue =3;
fillArray(array,initialValue);
}
}
Explanation:
Create the function with two parameter first is array and second is integer.
Then, declare the variable and store the size of array.
Take the for and fill the array from the incremented value of initialValue by 1 at every run of loop.
After loop, print the element of the array.
Create the main function which is used for calling the function and also declare the array with size 5 and initialValue with 3. After that, call the function with this argument.
Decision trees are onlyapplicable to problems under certainty.
True
False
Answer: False
Explanation:Decision tree is the tree like structured flowchart which is used for the evaluation of the possible outcomes or result of the particular problem. It usually has two or more branches as the the result node . Decision tree are applicable to many problems for solving it. So, decision trees is not only applicable on certainty problems but also on other problems as well. Therefore the given statement is false.
In a java program, package declaration .................... import statements.
A) must precede
B) must succeed
C) may precede or succeed
D) none
Answer: (A)must precede
Explanation:In java, import statements are important part that allows to import the whole package or any specific class in the package.It is used to import the built-in as well as user defined packages into the java source files and because of this your class can also refer to outside class of other packages as well in a direct way.
In a java program, package declaration must precede import statements.
In a Java program, the package declaration, if present, must be the first line in the source file, excluding comments. This is because the package declaration defines the namespace in which the classes are stored, and it is crucial for the Java compiler to know the package before it processes any import statements or class definitions.
Import statements come after the package declaration and before any class or interface definitions. They allow the program to refer to classes that are declared in other packages, making the code more modular and easier to manage. The typical order in a Java source file is:
1. Package declaration
2. Import statements
3. Class or interface definitions
If a source file does not have a package declaration, it is placed in the default package. Proper ordering is essential for the correct compilation and organization of Java programs.
The correct answer is A) must precede.
