    This is not the place where work is done for of you. Show us what you have tried, what didn't work, where you struggled, and ask specific questions. – bolov Dec 15 '13 at 08:43

I think that for x86 assembly, you can write

call   getchar

which will cause a trap. When the char is ready, it will be put in the eax register. You can then compare this value to the decimal value of char "0", which is 48.
