    A quick search pointed out to me that it has been suggested to you at least 3 times already:
    - not to use void main
    - do proper indentation
    but it does not appear to be registering.

    thanks sir heras..

    or if someone have already that kind of program.. share your blessings to me please, i don't know what to do anymore.. i'm just expecting and hoping that their's a ghost besides me and he will teach me how to work to it... i really hoping...

    sorry for asking a unforgivable favor... and don't judge, I know that I'm idiot when it comes to this, I can't really understand everything about programming, even I read some of the tutorials many times already.. i can't make my own logic, i think this field is not belong to me =(

    I like programming but programming doesn't like me i think ^^

    i don't know what to do anymore..
    Do 3 things
    1. read FAQ and change main to int main(void)
    2. indent your code properlyt - so it will be readable by people going to answer your questions
    3. Explain what output is expected and what output you are receiving
    All problems in computer science can be solved by another level of indirection,
    except for the problem of too many layers of indirection.
