The C language consists of number of library functions to perform various tasks. Frequently used functions are pre‒designed and pre‒compiled into library files, their prototypes can be found in the header files.

D HEADER FILES

File: Purpose

<stdio.h.> : Standard I/O library functions.

<stdlib.h> : Utility function such as string conversion routines, memory allocation routines, random number generator, etc.

<string.h> : String manipulation functions.

<math.h> : Mathematical functions.

<ctype.h> : Character testing and conversion functions.

<time.h> : Time manipulation functions.

<assert.h> : Putting diagnostics into programs.

<errno.h> : Reporting error conditions.

<float.h> : Describing floating‒point types.

<limits.h> : Describing integer types.

<local.h> : Formatting numeric values.

<setjmp.h> : Bypassing default function call and return conventions.

<signal.h> : Handling signals.

<stdarg.h> : Writing functions with an arbitrary number of arguments.

<stddef.h> : Common definitions.

Note: The following function parameters are used in header files:

i - integer argument

c – character type argument

s – string argument

u - unsigned integer argument

d - double precision argument

l - long integer argument

f - file argument

P - pointer argument

(*)- denotes a pointer
