Multifunction Program

MULTIFUNCTION PROGRAM

One advantage of the C++ language is the use of a function which can behave like a traditional function or a procedure. A function may call one more functions and so on. There is no restriction in C++ for calling the number of functions in a program. It is advisable to break a complex problem into smaller and easily manageable parts and then define a function. Control will be transferred from the calling portion of a program to the called function block. If the called function is executed successfully, then control will be transferred back to the calling portion of a program. In this type of multifunction program, transfer of control between the calling portion and a called function block is always in overhead.

    For example, a multifunction program segment is shown below.

            function1( )

           {

                  void function2 ( );

                  void function4(); // function declaration

                  

                  function2();

 

                  function4()

                  

           }

          function2()

          }

                void function3(); // function declaration

                

           function3 ();

               

         }

        function3()

        {    

                   

       }

       function4()

      {

                  

      }

PROGRAM

A program to demonstrate the transfer of control between the multifunction program.

    // multifunction declaration

   #include <iostream.h>

   void main (void)

   {

       void funct1 (void) ;

        cout << “ inside the main \n” ;

        cout << “ Komputer \n” ;

        funct1 ( ) ;

   }

   void funct1 (void)

   {

       void funct2 (void) ; / / function declaration

       cout << “ inside the function 1 \n” ;

       cout << “ kompu \n” ;

       funct2 ( ) ;

   }

   void funct2 (void)

   {

       cout << “ inside the function 2 \n” ;

       cout << kompu \n” ;

   }

Output of the above program

    inside the main

   komputer

   inside the function 1

   kompu

   inside the function 2

   kompu
