Cpp program to sum two numbers

In this tutorial, we will discuss the topic of Cpp program to sum two numbers
In this topic, we will learn how to add two numbers in C++ programming language

Find Sum to numbers Example- 1

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int f_no=45, s_no=35,sum;//variable declaration
    sum=f_no+s_no;  //find sum of integers
    cout << "sum of two numbers: "<<sum<< endl;//display result
    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Sum of two numbers: 80

Program 2

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int f_no, s_no,sum;
    cout << "Enter the first number: "<< endl;
    cin>>f_no;//get input from user for f_no
    cout << "Enter the second number: "<< endl;
    cin>>s_no;  //get input from user for s_no
    sum=f_no+s_no;  //find sum of numbers
    cout << "sum of two numbers: "<< endl;
    cout <<f_no<<" + "<<s_no<<" = "<<sum<< endl;
//display the result
    getch();
    return 0;
}

When the above code is compiled and executed, it produces the following results

Enter the first number:
75
Enter the second number:
65
sum of two numbers
75 + 65 = 140

In this program, the user has entered two integer values. These two values are stored in variables f_no, s_no.

Then both of values are added using plus (+) operator and stored in sum variable.

Finally, the sum is displayed on the screen
