Thread: Infinite Loop

Hi,
I have been busy trying out a program which emulates the basic functions of a cell( well presently only one basic function) but i have run into a hitch. The program doesn't display my output! and i don't understand why, any help is appreciated

O_o

An offhand guess says that you aren't ever actually calling any routines which dump any output.

Soma

don't call srand() more than once. only the last call will have an effect anyway. also, your formatting could use some work. try to be consistent with bracket placement and indentation.
