I have a problem with the C++ calculator in chapter 6. I entered the program and when I tried to compile it. I received two errors:
error LNK2019: unresolved external symbol _WinMain@16 referenced in function __tmainCRTStartup. Fatal error LNK1120: 1 unresolved externals. I've check all of the functions with that in the book and could find no errors. I did the CLR version and it works fine. I'm using Visual Studio 2008 standard could there be a change from the 2005 version.
