Comments in C

Comments in C language are used to provide information about lines of code. It is widely used for documenting code. There are 2 types of comments in the C language.

  1. Single Line Comments
  2. Multi-Line Comments

Single Line Comments

Single line comments are represented by double slash \\. Let’s see an example of a single line comment in C.

[cc lang=”bash” escaped=”true” width=”auto” nowrap=”0″ theme=”blackboard” line_numbers=”off” ]
#include
int main(){
//printing information
printf(“Hello C”);
return 0;
}        [/cc]

Output:

Hello C

Even you can place the comment after the statement. For example:

[cc lang=”bash” escaped=”true” width=”auto” nowrap=”0″ theme=”blackboard” line_numbers=”off” ]
printf”Hello C”//printing information[/cc]

Multi Line Comments

Multi-Line comments are represented by slash asterisk \* … *\. It can occupy many lines of code, but it can’t be nested. Syntax:
/*code
to be commented
*/
Let’s see an example of a multi-Line comment in C.
[cc lang=”bash” escaped=”true” width=”auto” nowrap=”0″ theme=”blackboard” line_numbers=”off” ]#include
int main(){
/*printing information
Multi-Line Comment*/
printf(“Hello C”);
return 0;
} [/cc]
