C++ Single & Multiline comments

Comments are pieces of source code discarded from the code by the compiler. They do nothing. Their purpose is only to allow the programmer to insert notes or descriptions embedded within the source code.

C++ introduces a new comment symbol // (double slash), comments starts with a double slash symbol and terminate at the end of line.

Types of C++ comments

  1. Single line comment
    // your comment goes here...
  2. Multi line comment
    /* your comment goes here... */

Comments using single line comment symbol

    // This is an example to print Hello.
    // Author : includehelp.com. 
    // Date : 13-02-2012.

Comments using multi line comment symbol

     /* This is an example to print Hello.
        Author : includehelp.com. 
        Date : 13-03-2012.
     */

Basic use of Comments

Basically we use comments in long coding, as there are thousands of lines of codes and its really hard to remember each and every line code's usage. So we do make a comment in the side, so that user can easily get for what a line is used.

That's also considered as a good practice to write code as other users can easily get your code.

So do not forget to use comments next time.
