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. -There are two different ways of marking a line as a comment: - - - -Example -------- - -:: - - x = 5; // This is a single line comment. Anything after the slashes is a comment - // to the end of the line - - /* this is multiline comment - use it to comment out whole blocks of code - - if (gwb == 0){ // single line comment is OK inside a multiline comment - x = 3; /* but not another multiline comment - this is invalid */ - } - // don't forget the "closing" comment - they have to be balanced! - */ - - - -**Tip** -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. - - |
