I've been typing a sample program in and it's been working. Recently typed it in again, and it's not working now. I've retyped it over and over and keep getting this error:
[Linker Error] Unresolved external 'WinMain' referenced from C:\PROGRAM FILES\BORLAND\CBUILDER6\LIB\C0W32.OBJ
Why has this problem started to show up? What needs to be done to troubleshoot this problem?
