That isn't C# code, it is C code.

I fix it....
what about my question?

[poncho4all]

I dont even know if you can do this with the new compilers
int ch[8][8]={0}

Here this about this while
while ((abc>4)||(abc<1))

its never gonna work, something bigger than 4 and less than 1 but your choices are 1 to 4

Im guessing your looking for
while(abc <5 && abc >0)

ITS int main() NOT void main and this is C code

EDIT:
Havent checked but i noticed i made a mistake

in the while statement i didnt noticed that you are looking for bad selection so take no notice of that my bad

I compiled your code gave me no errors

ok but how u can explain in Microsoft Visual Studio 2008 there is no compiler error?
and u can see if there other things that can do error?

After obfuscation of OP's code, right?!!

[poncho4all]

Im guessing your teacher tested the problem and there might be a runtime error. Dunno i didnt had any Build errors.

you have any idiea why my teacher say so?

As stated previously, main should return INT not VOID. Microsoft's compiler is forgiving for this code, but g c c with the warnings turned up yields a few:

g c c -Wall -pedantic -o error error.c
error.c:19: warning: return type of ‘main’ is not ‘int’
error.c: In function ‘main’:
error.c:20: warning: missing braces around initializer
error.c:20: warning: (near initialization for ‘ch[0]’)
error.c:20:59: warning: C++ style comments are not allowed in ISO C90

First, thank you
second thing, about my teacher he is not really want to help
Third you can please write me the errors for the new code above:
