i get those 2 warning, how do i fix it, check the code in the attachment
c:\lottery\lottery\lottery.c(60) : warning C4013: 'getch' undefined; assuming extern returning int
c:\lottery\lottery\lottery.c(17) : warning C4101: 'tick' : unreferenced local variable
Without even looking at the code I can tell you the first error is likely because your compiler doesn't support getch(). The second is just telling you that you declared a variable called tick and you never use it in your program.
If you understand what you're doing, you're not learning anything.
OK, now stop posting a new thread every time you have a new compiler warning with your program.
See other threads.
