c# functions

/* Answer to: "c# functions" */

/*
  A function has the following syntax:
  <modifiers> <return-type> method-name(parameter-list)
  
  You can use the following modifiers with a local function:
  - async
  - unsafe
  - static (in C# 8.0 and later). A static local function can't capture local
  	variables or instance state.
  - extern (in C# 9.0 and later). An external local function must be static.
  
  There's an example below:

using System;
					
public class Program
{
	public static void Main()
	{
		Console.WriteLine(square(4)); // Returns '16'
		Console.WriteLine(cube(4)); // Returns '64'
	}
	
	public static int square(int n)
	{
		return n * n;
	}
	
	public static int cube(int n)
	{
		return n * n * n;
	}
}

how to define a function in c#

//The "void" in this instance refers to the return type of this function
//This function won't have a return value.

functionName(Aninteger)
