Question

Create a program with the main function and one additional function.

The additional function asks for input from the user and returns the output back to the main function for display.

This is for c++ and here is my code, could you guys please tell me what I am missing from the instructions. Thank you

#include <iostream>
using namespace std;
int sum (int, int);

int main()
{
    int n1, n2, total;
  
      
    cout << "Enter two numbers and I will add the two numbers \n";
    cin >> n1;
    cout << "Now give me another number";
    cin >> n2;
    total = sum(n1,n2);
    cout << "The sum of " << n1 << " and " << n2 << " is " << total << endl;
    return 0;
  
}

int sum (int num1 , int num2)
{
    return num1 + num2;
  
}

Your program is ok but as asks in the question "The additional function asks for input from the user and returns the output back to the main function for display."

so its called function with no argument with return value

#include <iostream>
using namespace std;
int sum ();

int main()
{
int total;
total = sum();
cout << " is " << total << endl;
return 0;

}

int sum()
{
int n1, n2, total;
cout << "Enter two numbers and I will add the two numbers : ";
cin >> n1;
cout << "Now give me another number : ";
cin >> n2;
total = n1 + n2;
cout << "The sum of " << n1 << " and " << n2 ;
return total;

}
