Introduction

In this tutorial, we’ll explore a C# programming problem that involves adding two numbers and returning their sum. We’ll create a function that takes two numbers as arguments and returns their sum.

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 AddNumbers that takes two numbers as arguments:

public static int AddNumbers(int num1, int num2)
{
  // Add the two numbers and return their sum
}

Step 2: Adding the Two Numbers and Returning Their Sum

We’ll use the + operator to add the two numbers and return their sum:

public static int AddNumbers(int num1, int num2)
{
  return num1 + num2;
}

Putting It All Together

Here’s the complete code for the AddNumbers function:

public static int AddNumbers(int num1, int…
