How to C++ Program to Add Two Numbers

Here, you will learn and get the example code of C++ Program to Add Two Numbers using two different methods.

First we will get two numbers from the user as input, calculate the result, and print result as output.

C++ Program to Add Two Numbers

#include<iostream>

using namespace std;

int main()

{

int n1, n2, sum;

cout<<"Enter Two Numbers: ";

cin>>n1>>n2;

sum = n1+n2;

cout<<"\nSum = "<<sum;

return 0;

}

Output

#include<iostream>

using namespace std;

int sum(int,int);

int main()

{

int n1, n2, result;

cout<<"Enter Two Numbers: ";

cin>>n1>>n2;

result = sum(n1,n2);

cout<<"\nSum = "<<result;

return 0;

}

int sum(int a,int b)

{

return(a+b);

}

Output
