Structure of C++ program :

it is divided into 5 sections  

Document section

Linkage section

Global declaration

Main program section

Global data section

       

1. Document section:

• This section contain information about program on program heading
• It is provided by using comments
• c++ provide 2 types of comments

1. single line(//)
2. Multi line (/* *\)

Linkage section : C preprocessor directive section It is a programming     (# include)

• Any operation which has to be performed before compile program are defined this section

 

Global declaration :

It is used to declare global variable and function and types

Main program            

void main() { }                                 Main without arguments   void main(int arg c, char *arg[])    Main with arguments { }  

Global definition :

Definition functions and types which are declared inside global declaration void Main(int argc, char *arg v[], char *array) { }

• Compiler works as translation program between high level languages to low level language.
• Main is not recognized by compiler it is recognize by Linker 1
