Comments

You can include comments to explain code in your program by enclosing the text with /* and */ characters. If the /* character sequence is located within a string literal or a character constant, the compiler processes them as "normal" characters and not as the start of a comment.

You cannot nest comments. To comment blocks of code, enclose the block within the #if and #endif statements, as shown below:

#if 0

#endif
