    Hi,
    Yes, you are right but 0 denotes false in C.
    If value of one , 0 is applied. Then the next printf will not be executed.
    But we get "one is defined" how ?

    #define one 0
    This directive defines "one".

    #ifdef one 
printf("one is defined ");
#ifndef one
printf("one is not defined ");
    These directives check whether "one" is defined or not, irrespective of the value "one" takes.
