Question

write a program to input three numbers and print the sum and averages of three numbers​

Answer 1

This program is in Java.  

import java.util.*;

public class AverageCalculator {

   public static void main (String [] args) {

       //Taking input from the user

       Scanner sc = new Scanner(System.in);

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

       double num1 = sc.nextDouble();

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

       double num2 = sc.nextDouble();

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

       double num3 = sc.nextDouble();

       //Main part comes here

       double Average = (num1 + num2 + num3) / 3;

       double sum = num1 + num2 + num3;

       System.out.println("The sum of the following numbers is " + sum);

       System.out.println("The average of the given numbers is " + Average);

   }

}

Output:

Enter the first number: 30

Enter the second number: 31

Enter the third number: 28

The sum of the following numbers is 89.0

The average of the given numbers is 29.666666666666668
