C# Programming Tutorial 4 - Comments

Comments are useful for explaining the purpose of a piece of code or how it works. Comments can also be used to identify the author of code or when it was created or last updated.

In C# the // characters (two forward slashes) are used to add comments to your code. Any text on a line after the two forward slashes will not be treated as code. Comments are useful as they contain notes about what is happening in the code and can help others understand the algorithm. They won’t change the way a program runs and won’t be visible in the working program.
