Introduction

In this tutorial, we’ll explore a C++ programming problem that involves incrementing a number by +1 and returning the result. We’ll create a function that takes a number as an argument, increments it by +1, and returns the result.

By the end of this post, you’ll have a better understanding of how to work with variables, data types, and functions in C++.

Step 1: Defining the Function

First, let’s define a function called Addition that takes an integer as an argument:

int Addition(int number)
{
  // Increment the number by +1 and return the result
}

Step 2: Incrementing the Number by +1 and Returning the Result

We’ll use the + operator to increment the number by +1 and return the result:

int Addition(int number)
{
  return number + 1;
}

Putting It All Together

Here's the complete code for the Addition function:
