Structure of a C++ Program
     
1.) Header file (Include file)
2.) Member function definition
3.) Class declaration
4.) Main function


1. Header File:
In this section, we add header files and resource files. These files provide definition for function and object used in a program.



2. Member Function Definition:
In this section class member, function and other functions are defined.
Ex:

demo :: fun()
{
            Definition
}



3. Class Declaration:
In this area class is defined.
Ex:

class demo
{
            Member variables and functions
};



4. Main Function:
This is special type of function that is called at the beginning of program execution. Each program must have one main function.

int  main()
{
            return 0;
}
