Using Functions as Arrays

This is a C code for using functions as arrays.

We use array of function pointers. Here is sample code

  // array of functions
  #include

  // -- FUNCTION PROTOTYPES --
  void func1();
  void func2();
  void func3();
  void func4();
  void func5();
  // -- ENDS --

  void main()
  {
   // notice the prototype
   void (*ptr[5])();

   // arrays are made to point
   // at the respective functions
   ptr[0]=func1;
   ptr[1]=func2;
   ptr[2]=func3;
   ptr[3]=func4;
   ptr[4]=func5;

   // now the array elements
   // point to different functions
   // which are called just like
   // we access the elements of
   // an array
   for(int i=0;i<5;i++)
     (*ptr[i])();
  }

  // -- FUNCTIONS DEFINITION --
  void func1()
  {
   cout<<"Called Func1!\n";
  }

  void func2()
  {
   cout<<"Called Func2!\n";
  }

  void func3()
  {
   cout<<"Called Func3!\n";
  }

  void func4()
  {
   cout<<"Called Func4!\n";
  }

  void func5()
  {
   cout<<"Called Func5!\n";
  }
  // -- ENDS --
