compile error

[rvelez3]

I get the following error when I compile: All outputs are up-to-date.
1>MSVCRTD.lib(crtexe.obj) : error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup
1>C:\Users\Reynold\documents\visual studio 2010\Projects\studentdb\Debug\studentdb.exe : fatal error LNK1120: 1 unresolved externals
1>Build FAILED.
I am using Visual Studio 2010, and I may have changed a setting by mistake!!
