Chapter-1

BASICS


    To develop a program in c language one has to learn about
  1.   Header Files
  2.   Pre Defined funtions
  3.   Variables
  4.   Data types
  5.   operators
  6.   keywords
  •  Header Files : 
            The different types of header files present in c-language are


           #include<stdio.h>
           #include<conio.h>
           #include<math.h>
           #include<string.h>
           #include<dos.h>
           #include<graphics.h>
           #include<alloc.h>
        

          These header files contain pre defined functions like;
           #include<stdio.h>  --->>  printf( ),scanf( ) 
           #include<conioh>  --->>  getch( ),clrscr( )
           #include<math.h>  --->>  sqrt( ),pow( )
           #include<string.h>  --->>  strcpy( ),strrev( )
