[Because you crossposted your article to (among other places) comp.lang.c, 
this reply assumes you are programming in C.]

If you have a C99 compiler, // comments are legal. If you have a C90 
compiler, they are not.

If you have a C90 compiler, implicit int return type is legal. If you have a 
C99 compiler, it is not. So, either way, you have a syntax problem.

The behaviour of fflush on input streams is undefined.

What if the user types something that isn't a number?
[i][i][i]

The 'more' is a single character. %s expects a pointer to an /array/ of 
characters. You meant %c, not %s. In any event, an unadorned %s is unwise 
(because of buffer overruns).

Fix those problems, and re-test. This will uncover more problems, but should 
also lead to greater understanding.

Please pick your newsgroups more carefully next time. Thanks. (I think you 
are best off in alt.comp.lang.learn.c-c++ at present, but comp.lang.c is a 
decent alternative in this case. The other groups to which you posted are 
really implementation groups, not language groups.)[/i][/i][/i][/i]
