C++ add two numbers using the function

Here we will learn how to add two numbers by creating function in C++.

Let’s learn this with help of example.

Code: -

#include <iostream>
using namespace std;
int add_two_no(int a, int b);
int main(){
  int first_num, second_num, sum;
  cout << "Enter the first number: ";
    cin >> first_num;
    cout << "Enter the second number: ";
    cin >> second_num; 
    sum = add_two_no(first_num, second_num);
   cout << "Sum of " << first_num << " and " << second_num << " is: " << sum << endl;
    return 0;
}
int add_two_no(int a, int b){
    return (a + b);
}

Output: -

Add two numbers using the function in C++.

Explanation:-

In the above code, three integer variables are named first_num,second_num, and sum.

After that, the user is asked to enter inputs, and it is stored in variables first_num and second_num.

After that user-defined function is created named add_two_no for calculating the addition of two numbers and is called for the same purpose.

The user-defined function named add_two_no passes two numbers as an argument/parameter and returns the sum of the two numbers.

And in the last is displayed using cout statement.
