Comments in C language

 Comments in C language

Comments in C language are used to provide extra details about various aspects of a program. They are usually included at the start of a program to indicate its purpose, its author, and the date on which it was written. They also provide clarification about complicated statements in the program.

There are two types of comments used in C. These are single-line comments and Multi line comments. Details about these are given as follows:

Single comments

These comments are only on a single line and cannot move beyond that. They are represented using a double slash (//). An example of single-line comments in C is:

// Program to display single line comments // Studyopedia - Never Stop Learning #include < stdio.h > int main(void) { int a = 5; printf("Comments in C - Studyopedia\n"); printf("\n----------------------------\n"); printf("Hello\n"); // Printing Hello on screen printf("Value of a is %d", a); // Printing value of a return 0; }

The output of the above program is:

Multi- line comment

These comments can be extended over multiple lines. They are represented using /* i.e slash asterisk (/*……….*/). Multi-line comments cannot be nested. An example of multi-line comments in C is:

/* Program to display multi-line comments Studyopedia - Never Stop Learning */ #include < stdio.h > int main(void) { int a = 10; printf("Comments in C - Studyopedia\n"); printf("\n-------------------------\n"); printf("Hello\n"); printf("Value of a is %d", a); return 0; }

The output of this program is:
