And here is the error flagged by the compiler :

Code:

**********\beta_2.c(120) : warning C4047: '==' : 'void (__cdecl *)()' differs in levels of indirection from 'const int '
**********\beta_2.c(137) : error C2449: found '{' at file scope (missing function header?)
**********\beta_2.c(164) : error C2059: syntax error : '}'
**********\beta_2.c(201) : warning C4553: '==' : operator has no effect; did you intend '='?
Error executing cl.exe.

beta_2.obj - 2 error(s), 2 warning(s)

thanks. a lot for your suggestions. i found the error(";")... .

This MainMenu() function will eliminate the need to call main() from within your program.
Control to all functions loops out from MainMenu(), and then returns to it, perhaps with
a status variable if there is much likelihood of an error. Like reading a file that may not
be in the right directory, etc.

This is not tested code, btw, just a recommended approach to improving your program via a menu function.
