C++ program to add two integer numbers using function

In the last program [<a href="https://nerdutella.com/q1120-C-plus-plus-program-to-add-two-integer-numbers" "="" style="box-sizing: border-box; color: rgb(0, 0, 255);" data-mce-href="https://nerdutella.com/q1120-C-plus-plus-program-to-add-two-integer-numbers">C++ program to add two integer numbers], we discussed how to take input and find the sum of two integer numbers?

In this program we are doing the same but using a user defined function, this program will take two integer numbers are calculate the sum/addition of them using a user defined function.

The function addition is used to calculate addition of the numbers, in this program we will pass the entered integer numbers and function will return the addition of the numbers.
