The Basics:

A function allows you to encapsulate a piece of code and call it from other parts of your code. You may very soon run into a situation where you need to repeat a piece of code, from multiple places, and this is where functions come in.

In C#, they are basically declared like this:

To call a function, you simply write its name, an open parenthesis, then parameters, if any, and then a closing parenthesis, like this:

Here is an example of our DoStuff() function:

The first part, public, is the visibility, and is optional.

If you don't define any, then the function will be private. More about that later on. Next is the type to return.

C# function vs method

It could be any valid type in C#, or as we have done it here, void. A void means that this function returns absolutely nothing. Also, this function takes no parameters, as you can see from the empty set of parentheses, so it's actually just a tad bit boring.

Let's change that:

We've changed almost everything. The function now returns an integer, it takes two parameters (both integers), and instead of outputting something, it ma
