Link Section

§Header Files

 #include<x.h>  à where x is a header file like such as :

 string.h---àfor string handling function

          stdio.h ----àfor  standardized input and output functions

                       math.h ---àfor mathematical functions 

                      alloc.h ---àfor dynamic memory allocation

         conio.h --àfor clearing the screen

         stdlib.h --àfor some miscellneous functions

 Source Code file

Contain source code of the program 

Object Files

Generated by the compiler  as a result of processing the source code

Binary Executable File

Generated by the linker  as a result of production of binary files through the object     filesthat can be directly executed on Windows  operating system in .exe extension

Definition Section

Eg/ user define header file

          #define MAX 50 etc…  

*Here MAX is a constant whose value is 50

Global Declaration Section

When the declare the variable before the main function of program  

Main Section

§It consist of Declaration part and executable part of the program

§Eg/    main()

               {

                       declaration part // int a,char b,float c etc..

                       executable part //

                 }

Subprogramming Sectio

In sub programing section we may create a function for a particular task and call to main function.

             We may create more than one function in a single program

     §Eg /         Function1()

                             Function2()

                                     ………..FunctionN()
