Question

I’m having two errors everytime I try to debug a simple project in Visual Studio 2010.

Error   1   error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup   C:\Users\Fighter\Documents\C++\Point\Point\MSVCRTD.lib(crtexe.obj)  Point

Error   2   error LNK1120: 1 unresolved externals   C:\Users\Fighter\Documents\C++\Point\Debug\Point.exe    1   1   Point

this is a simple code I’m using to try my program in VS :

class Point

{
private:
int x;
int y;

};

The problem is that this thing works great in Code::Blocks but whith VS it gives me those errors.

What’s the problem here.

Thanks

Your program needs a main() function to be valid.

int main(int argc, char* argv[]) 
{
    Point p;
    return 0;
}
