Comments in Programming

What is Comments and how it is use?

Comments is the Essential element of all programming language.And It is use mostly all top most languages like

• C
• C++
• C#
• JAVA
• Python
• PHP
• Perl

Comments are use to describe the logic ,methodology and for remembering  the code working.
Every Programmer must use these comments.Actually this is use in each and every programming language.
Let consider ,if you write some programming code and after 1 month you see those code then its very hard to understand the logic behind the code.

There are different type of comments
Single line Comment  //
Multi Line Comment  /*   */

Complier leave the comment and  understand that this is a human code not for me


Example

int number;   //This is declaration

Now compiler only work on "int number;" and leave the remaining part of this line


Similarly case with multi line comments

int number =4;
number++;
/*Initialization the integer number
and increment the number value 
by 1 value;
*/
