Currently supports 8 programming languages (Python, Java, JavaScript, C#, Ruby, C++, C, PHP)

Syntax for comments in popular programming languages:

C#:

single line: //
multi-line: /*  .. */
xml-doc comments: ///

Java:

single line: //
multi-line: /*  .. */

Javascript:

single line: //
multi-line: /*  .. */

C, C++:

single line: //
multi-line: /*  .. */

PHP:

single line: // or #
multi-line: /* ... */

Ruby:

single line: #
multi-line: =begin, =end

Python:

single line: #
multi-line: # followed by #

Note

In java, c#, javascript, C, C++

	1. /*comment 1*/ will be considered as a block line comment but the number of lines within the block will be 0 (as the block starts and closes in the same line)

	2. /* comment 1 starting on line 1
  		   *
  		   *
 		   */

'Total # of comment lines within block comment' will be 3 as the comment starts on the first line

In Python

	1. print "Hello world!" # printing hello world ---- (1)
 	        #comment explaining the next line          ---- (2)

In this case, (1) will be considered as an inline comment and (2) as a single line comment. ie. (1) and (2) together will not be considered as a multi-line   block

	2. '#' within docstring comments will be considered as a comment
