Use of '#if' as '#ifdef'


    #include <iostream.h>
    #include <conio.h>
    #define  print  1           /* macro 'print' definition */
    void main()
    {
        int a = 10 ;
        clrscr () ;
        a = a + 1 ;
        #if defined (print)   /* if macro 'print' defined */
            cout << "a = " << a ;
        #endif
        getch () ;
    }
