Your feedback will help me make myself a better programmer
OK, here goes:
First and foremost, format your code properly.
#include <conio.h> -- don't use it. It's not portable and there's nothing in there you really need #include <stdio.h> -- this is (supposedly) a C++ program. Don't use C headers #include <stdio.h> -- why twice? int main() -- where is yourreturn statement? You should be getting a compiler warning.
system("c:\\batch.bat"); -- why are you executing a batch file? system("cls"); -- clearing the screen is annoying to the user. You don't need to do it. break; halts execution so the next line cannot possibly be executed. goto IMUM; -- there is rarely ever a need for GOTO. Don't use them. And since you used it after break; , you can't get to it anyway. You should have compiler warnings about this.
And if you've been programming for 12 days, why are you writing a program that can f'up your system?
All in all, I consider this a terrible program. Sorry.
