Part1) Given 3 integers, output their average and their product, using integer arithmetic.
Mrac [35]

Answer:

The program is as follows:

#include <iostream>

#include <iomanip>

using namespace std;

int main(){

   int num1, num2, num3;

   cin>>num1>>num2>>num3;

   cout << fixed << setprecision(2);

   cout<<(num1 + num2 + num3)/3<<" ";

   cout<<num1 * num2 * num3<<" ";

   return 0;

}

Explanation:

This declares three integer variables

   int num1, num2, num3;

This gets input for the three integers

   cin>>num1>>num2>>num3;

This is used to set the precision to 2

   cout << fixed << setprecision(2);

This prints the average

   cout<<(num1 + num2 + num3)/3<<" ";

This prints the product

   cout<<num1 * num2 * num3<<" ";
