C Keywords must be in your information because you can not use them as a variable name. This tutorial describes various Keywords available in C.
You can't use a keyword as an identifier in your C programs; it's reserved words in the C library and used to perform an internal operation. The meaning and working of these keywords are already known to the compiler.
C Keywords List
A list of 32 reserved keywords in the C language is given below:
| auto | double | int | struct |
| break | else | long | switch |
| case | enum | register | typedef |
| char | extern | return | union |
| const | float | short | unsigned |
| continue | for | signed | void |
| default | goto | sizeof | volatile |
| do | if | static | while |
Example Where and How Keywords are Used in the Program
Example:
#include<stdio.h>
int main()
{
float a, b;
printf("Showing how keywords are used.");
return 0;
}In the above program, float and return are keywords. The float keyword is used to declare variables, and the return is used to return an integer type value in this program.
