    TITLE  :  Defining and Using Arrays of Pointers to Functions




  The following demonstrates how to define and initailize an array
  of pointers to functions.  In addition, calling a function whose
  pointer is contained in such an array is demonstrated.

  #include <stdio.h>

  void (*p[5])();            // p is defined to be an array of
                             // 5 pointers to functions taking
                             // no (void) paramaters and returning
                             // nothing (void)

  void foo1(void) { printf("Hello, in function foo1\n"); }
  void foo2(void) { printf("Hello, in function foo2\n"); }

  main()
  {
     p[0]=foo1;  // Assign pointer at array index 0
                 // to point at function foo1.
     p[0]();     // Now call foo1


     p[1]=foo2;  // Assign pointer at array index 1
                 // to point to function foo2.
     p[1]();     // Now call foo2
  }
