That's correct.

Same goes for -=  *=  and  /=

It essentially just means "Do this, to this variable".


sum += 7  "Add 7 to sum"
result *= 10  "Multiply result by 10"
So on, and so forth.

Write a program that prompts the user to enter the number of integer numbers you need to enter, then ask user to enter these int
nadya68 [22]

Answer:

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

 Scanner ob = new Scanner(System.in);

 System.out.println("How many numbers? ");

 int n = ob.nextInt();

       int[] arr = new int[n];  

 for (int i=0; i<n; i++) {

     System.out.print("Enter the number: ");

     arr[i] = ob.nextInt();

 }

    System.out.println(indexOfLargestElement(arr));

}

public static int indexOfLargestElement(int[] arr) {

    int max = arr[0];

    int maxIndex = 0;

    for (int i=0; i<arr.length; i++) {

        if (arr[i] >= max) {

            max = arr[i];

            maxIndex = i;

        }

    }

    return maxIndex;

}

}

Explanation:

Create a method called indexOfLargestElement that takes one parameter, an array

Initialize the max and maxIndex

Create a for loop iterates throgh the array

Check each element and find the maximum and its index

Return the index

Inside the main:

Ask the user to enter how many numbers they want to put in array

Get the numbers using a for loop and put them inside the array

Call the indexOfLargestElement method to find the index of the largest element in the array

Why did hockey champion Haley wickenheiser feel angry after the Bach said the IOC would make a decision in the next month?
aliina [53]

Haley wickenheiser felt angry after the Bach said the IOC would make a decision in the next month as the IOC says the games will be held no later than summer 2021 but they will still be called the 2020 Tokyo Olympics.

Explanation:

  • The Tokyo Olympics were postponed until 2021 on Tuesday, ending weeks of speculation that the games could not go ahead as scheduled because of the coronavirus pandemic.
  • The International Olympic Committee made the decision after speaking with Japanese Prime Minister Shinzo Abe and local organizers.
  • The IOC said the games will be held not later than summer 2021 but they will still be called the 2020 Tokyo Olympics.
  • “President Bach said he will agree ‘100%,’ and we agreed to hold the Tokyo Olympics and Paralympics in the summer of 2021 at the latest,” Abe said, saying holding the games next year would be “proof of a victory by human beings against the coronavirus infections.”
  • The decision came only a few hours after local organizers said the torch relay would start as planned on Thursday.

Define a method printFeetInchShort, with int parameters numFeet and numInches, that prints using ' and " shorthand. End with a n
worty [1.4K]

Answer:

The program to this question as follows:

Program:

//header file

#include <iostream> //defining header file

using namespace std;

void printFeetInchShort(int numFeet,int numInches); //decalring method printFeetInchShort  

void printFeetInchShort(int numFeet,int numInches)//defining method printFeetInchShort

{

cout<<"height: "; // print message

cout<<numFeet<<"\'"<<""<<numInches<<"\""; //print value

}

int main() //defining main method

{

int numFeet, numInches; //defining integer variable

cout<<"Enter height feet: "; //print message

cin>>numFeet; //input value by user

cout<<"Enter height inches: "; //print message

cin>>numInches; //input value by user

printFeetInchShort(numFeet,numInches); //calling method printFeetInchShort    

return 0;

}

Output:

Enter height feet: 5

Enter height inches: 9

height: 5'9"

Explanation:

In the above C++ language program, first, a header file is included, that uses the basic function, in the next step, the "printFeetInchShort()" method is defined, in the method two integer variables passed as a parameter, inside this method a print function "cout" is used, that print user input value with single and double quote.

Then the main method is declared, inside this method two integer variables "numFeet and numInches" are defined, which is used to take input value by user and pass the value in "printFeetInchShort()" function parameter and call the function.

What are the benefits of writing functions that use parameters and return List 2 please and explain what is return
Ratling [72]

<u>Answer and explanation:</u>

There are many benefits of writing functions that use parameters and return. Some of them are:

1. Flexibility: With functions having parameters, several values of the parameters can be used at invocation time thereby making the application flexible. For example, given the following function in Java.

<em>public void showName(String name){</em>

<em>    System.out.println("Your name is " + name);</em>

<em>}</em>

To call this method (function), the programmer could use various values for the name parameter used in the function like so:

showName("John");

showName("Doe");

If the function didn't have a parameter, it is possible it will only print a hardcoded name every time the function is called.

2. Scope Control: When a function is allowed to return a value, it helps to work around scope issues since variables declared within a function are limited to that function and do not exist outside the function. This means that the values of these variables cannot be used anywhere else outside the function in which they are being declared. However, if the function returns a value, the value can be used anywhere else in the program.

For example:

<em>public String getDouble(int x){</em>

<em>    int y = x * 2</em>

<em>    return y;</em>

<em>}</em>

The function above returns twice the value of the argument supplied to it. Since the integer variable y is declared within the function, it's value cannot be used outside the function. However, since the value is being returned by the function, it could be used anywhere the function is being called. Thanks to the return keyword.
