LIBRARY IN C

WHAT IS LIBRARY IN C:

A library is collection of in built functions to perform various operations.They are grouped together as a single unit for re-usability.

If the programmer wishes to use a function contained in library,they only need to specify the function name,following the function prototype i.e, correct call or return condition.Program must #include statement at the beginning of the program.This is known as a header file.The compiler will then internally link the standard library code by default.

SOME COMMONLY USED HEADER FILES ARE:

stdio.h - for file input and output operation

string.h - for string operation

time.h - for manipulating date and time

stdlib.h - for memory management utility functions like calloc() and malloc().
