A very simple mistake...

[Vijay]

I just wanted to create a programme in C, which will count up from 1 to 20.
Heres the script, but for some reason, theres a mistake and it won't work, I don't see whats wrong with it.
Can you find the mistake :surprised :

main()
{
    int Nth;
    int lower, upper, step;
    
    upper = 20;
    lower = 1;
    step = 1;       /* step size */
    
    Nth = lower;
    while (Nth <= upper){
        Nth = Nth + step;
        printf("%d", Nth);
        getchar();
    }
}

Don't bother, I found the mistake.

main()
{
    int Nth;
    int lower, upper, step;
    
    upper = 20;
    lower = 1;
    step = 1;       /* step size */
    
    Nth = lower;
    while (Nth <= upper){
        Nth = Nth + step;
        printf("%d", Nth);
        getchar();
    }
}

"it won't work" isn't a very helpful description of the situation.
Did you try using the C compiler? Did you provide input? What did happen?

I'm guessing that you're hung on buffered I/O. See `man 3 fflush`.

I also notice that it will print 2-21 since you have incremented before the print. And you may find the formatting unsatisfactory.

main should return an int

SHOULD ---
It also should have argc and argv arguments .....

But I perceive that the inquirer is not yet ready for such subtleties.

Yes, I know I left the arguments out at the very beginning. And I said so.

You did? I don't see where you declared that omission.
