When experimenting with code, "commenting out" parts of your program is a convenient way to remove lines that may be buggy. This leaves the lines in the code, but turns them into comments, so the compiler just ignores them. This can be especially useful when trying to locate a problem, or when a program refuses to compile and the compiler error is cryptic or unhelpful.

Comments are lines in the program that are used to inform yourself or others about the way the program works. They are ignored by the compiler, and not exported to the processor, so they don't take up any space on the Atmega chip.

Comments only purpose are to help you understand (or remember) how your program works or to inform others how your program works.

[@ x = 5; // This is a single line comment. Anything after the slashes is a comment to the end of the line

// don't forget the "closing" comment - they have to be balanced!

Comments are parts in the program that are used to inform yourself or others about the way the program works. Comments are ignored by the compiler, and not exported to the processor, so they don't take up any space on the Atmega chip.

Comments

Comments are parts in the program that are used to inform about the way the program works. They are not going to be compiled, nor will be exported to the processor. They are useful for you to understand what a certain program you downloaded is doing or to inform to your colleagues about what one of its lines is. There are two different ways of marking a line as a comment:

• you could use a double-slash in the beginning of a line: //
• you could use a combination of slash-asterisk --> asterisk-slash encapsulating your comments: /* blabla */
