header file:- the c standard library contains files containing the function .these files are known as header file .Heaedr file provide function prototype ,definition for library function .Data tpe and constants used with the library function are also defined on them .
Some of these are :-
1.stdio.h:-this header file define type and macro needed for the standard i/o package .this defin i/o predefined stream e.g. stdin,stdout ,stderr.
2.string.h:- this header file declare several string manipulation and memory manipulation routine .the function are-
memccpy,stdcp,strtok.
3.math.h:- this header file declar prototype for the math function and math handlers .The routine in math.h file perform mathematical calculation and conversion.
4. stdlib.h:-this header file file declare several commonly used routine like conversion routine ,search routine .
