Write a C++ program to add two integers. Make a function add() to add integers and display sum in main() function.

In C++:

#include <iostream>

using namespace std;

int add(int a, int b){

   int c = a + b;

   return c;

}

int main(){

   int a, b;

   cout<<"Enter two numbers: ";

   cin>>a;

   cin>>b;

   cout<<add(a,b);

   return 0;

}

Explanation:

The add() function begins here

int add(int a, int b){

This adds the two integers

   int c = a + b;

This returns the sum of the two integers

   return c;

}

The main begins here

int main(){

This declares two numbers

   int a, b;

This prompts user for two numbers

   cout<<"Enter two numbers: ";

The next two lines gets the two numbers

   cin>>a;

   cin>>b;

This gets the sum of the two numbers from the add() function. The sum is also printed

   cout<<add(a,b);

   return 0;

}
