Here is a C++ program to find sum of two numbers. To find sum of two numbers in C++, we will first take two numbers as input from user using cin and store them in two local variable. Now, we will add two input numbers using addition operator ('+') and store the sum in third variable. Finally, we will print the sum of two numbers on screen using cout.

## C++ program to add two numbers using + operator

#include <iostream> using namespace std; int main() { float num1, num2, sum; // Taking input from user cout << "Enter Two Numbers\n"; cin >> num1 >> num2; // Adding two input numbers sum = num1 + num2; // Printing output cout << "Sum of "<< num1 << " and " << num2 << " is " << sum; return 0; }Output

Enter Two Numbers 4 3.5 Sum of 4 and 3.5 is 7.5

## C++ program to find sum of two numbers using function

In this program, we will use a user defined function **float getSum(float a, float b)** which takes two floating point number as input and returns the sum of input parameters.

#include <iostream> using namespace std; // Function to add two numbers float getSum(float a, float b){ return a + b; } int main() { float num1, num2, sum; // Taking input from user cout << "Enter Two Numbers\n"; cin >> num1 >> num2; // Adding two input numbers by calling getSum function sum = getSum(num1, num2); // Printing output cout << "Sum of "<< num1 << " and " << num2 << " is " << sum; return 0; }Output

Enter Two Numbers 3.2 4.5 Sum of 3.2 and 4.5 is 7.7
