Comments are lines or parts of lines not being processed. They serve to describe what happens within the program or to disable program statements.

The comments are of two types - end of line comments or multiline comments. See the following two options:

// This is an end line comment.
// Everything following the slashes until end of line is a comment.

integer count = 0; // Comment can follow the code

/* This is a multiline comment.
   Everything between starting and ending symbol is a comment. */
