Answer 2

#include<iostream>

using namespace std;

double add(double num1, double num2, double num3);

double avg(double sum, int n);

int main()

{

 double num1, num2, num3;

 double sum, average;

 cout << "Enter three Numbers :: ";

 cin >> num1 >> num2 >> num3;

 sum = add(num1 , num2, num3);

 

 average = avg(sum, 3);

 cout << "Sum = " << sum << endl;

 cout << "Average = " << average << endl;

 return 0;

}

double add(double num1, double num2, double num3)

{

   return num1+num2+num3;

}

 

double avg(double sum, int n)  

{

   return sum / n;

}
