1.	What Are Header Files And What Are Its Uses In C Programming?
Answer» Header files are also known as library files. They contain two essential things: the DEFINITIONS and prototypes of FUNCTIONS being used in a program. Simply PUT, commands that you use in C programming are actually functions that are DEFINED from within each header files. Each header file contains a set of functions. For example: stdio.h is a header file that contains definition and prototypes of commands like printf and scanf. Header files are also known as library files.
