Write a program which prompts the user to enter three intege

Write a program which prompts the user to enter three integers. The program then computes and displays their sum and average (displayed in the format 999.99)?

Solution

Solution.java

import java.text.DecimalFormat;//package for precision
import java.util.Scanner;//keyboard inputting

public class Solution {//main class
    public static void main(String args[]){//main method
   Scanner sc=new Scanner (System.in);
   System.out.println(\"enter number 1\");
   int num1=sc.nextInt();//keyboard inputting
   System.out.println(\"enter number 2\");
   int num2=sc.nextInt();//keyboard inputting
   System.out.println(\"enter number 3\");
   int num3=sc.nextInt();//keyboard inputting
   int sum=0;
   float avg;
   sum=num1+num2+num3;
   avg=(float)sum/3;

DecimalFormat df2 = new DecimalFormat(\"###.##\");
        System.out.println(df2.format(avg));
        }
  
  
  
}

output

enter number 1
112
enter number 2
112
enter number 3
111
sum = 335
avg 111.67

Solution.cpp

#include <iostream>//header file for input output function
#include <iomanip>//header for precision
using namespace std;//it tells the compiler to link std nnamespace

int main()
{//main function
    int num1,num2,num3,sum;
    float avg;//varaible declaration
   cout<<\"enter num 1 \";
   cin>>num1;//keyboard inputtging
   cout<<\"enter num 2 \";
   cin>>num2;//keyboard inputtging
   cout<<\"enter num 3 \";
   cin>>num3;//keyboard inputtging
   sum=num1+num2+num3;
   avg=(float)sum/3;//calculate avg
   cout<<\"sum = \"<<sum<<endl;
   cout<<\"avg = \"<<fixed<<setprecision(2)<<avg<<endl;

   return 0;
}

output

enter num 1 12                                                                                                                                                           

enter num 2 12                                                                                                                                                           

enter num 3 13                                                                                                                                                           

sum = 37                                                                                                                                                                 

avg = 12.33sh-4.3$
