    I wasn't a math major but 0!=1 couldn't happen.

    1!= 1 2!=2x1 3!=3x2x1 etc etc so since there is no subset of positive integers below zero, 0! like the square root of -1 would fall into the imaginary number category.

    AFAIK, I don't think it has any proof. It's just an assumption to ensure that while calculating permutations and combinations (among other things), you don't get stuck with a 0 in the denominator.

    I'm sorry i'm no maths expert. 0=0 to me, to think otherwisemakes no sense.

    Of course 0!=1

    Code:
    #include <stdio.h>
    
    main()
    {
    if(0!=1)
    printf("Hey! I'm right!");
    else
    printf("You Suck!");
    
    return 0;
    }
    (joke)
