Let’s have a glance at the list of Header Files in C programming language.
List of Header Files in C

| <math.h> | It defines common mathematical functions. |
| <stdio.h> | It defines core input and output functions |
| <stdint.h> | It defines exact-width integer types. |
| <inttypes.h> | It defines exact-width integer types. |
| <threads.h> | It defines functions for managing multiplethreads,mutexesandcondition variables |
| <locale.h> | It defines localization functions. |
| <float.h> | It defines macro constants specifying the implementation-specific properties of the floating-point library. |
| <limits.h> | It defines macro constants specifying the implementation-specific properties of the integer types. |
| <iso646.h> | It defines several macros that implement alternative ways to express several standard tokens. For programming in ISO 646 variant character sets. |

| <errno.h> | For testing error codes reported by library functions. |
| <assert.h> |
It contains the assert macro, used to assist with detecting logical errors and other types of bug in debugging versions of a program.
|
| <ctype.h> | It defines a set of functions used to classify characters by their types or to convert between upper and lower cases in a way that is independent of the used character set (typically ASCII or one of its extensions, although implementations utilizing EBCDIC are also known). |
| <complex.h> | It is a set of functions for manipulating complex numbers. |
| <uchar.h> | It contains types and functions for manipulating Unicode characters |
