************************************************ this is Just studying a code to be knocked in the book, I can make sure that there is no problem with the book, but when debugging on your computer, it is always a problem. The mistake is as follows: -------------------- Configuration: CPP1 - Win32 Debug -------------------- LINKING ... libcd.lib (CRT0.Obj): Error LNK2001: Unresolved External Symbol _mainDebug / cpp1.exe: Fatal Error LNK1120: 1 Unresolved ExternalSerror Executing Link.exe.
CPP1.EXE - 2 Error (s), 0 Warning (s) I have already got two days, there is no prawn to save the younger brother! There is no way to understand what is going on! I also knocked on a similar program before he had the same problem! I have started to suspect that it is no problem with my system! There is no way, thank you!
