Thread: Help for debugging a program

Dear friends,

I tried to do my homework and came to some ideas and I wrote a program. but it is not working properly. would be nice if you can check it and give some comments.

the orginal problem is:
Write a program, that enters an integer decimal number and a base number (<10), using a void function Input().
A funtion void To_Base() then converts this number to a number according to the entered base, after which a function Output() prints the results neatly
Use pointers! Array’s are not allowed!

and here is my codes:

Code:

/***********************************************************************\
|this program converts decimal number to base number			               |
|                                                                                                                                              |

oh Sorry I found the problem already. sorry for bothering.

I also edited the code in my first post aswell so it maybe useful for somone.
