I was missing a CSnake(); body, but now it shows 5 unresolved links :/ I"ll check it now. but the missing body CSnake constructor body is a good reason
In the CSnake class change this:
CSnake();
to this:
CSnake(void);
This makes a difference in some compilers.
CSnake();
to this:
CSnake(void);
This makes a difference in some compilers.
i have added the void, all the files are compiled well, but when i make a build, it gives me 5 linker errors
these errors are from CSnake's "sub" files , like a linked list and all the rest. But it worked, the thing is the snake worked.
I just wanted to imigrate it into win 32 API :/ :\
Shall i upload the whole code?

Have you implemented funcion bodies for MCPoint::MCPoint(int,int), CList::CList(void), etc. ?
Sometimes when I get linker errors I have to delete the .obj files in the debug folder.
This doesn't always work, but sometimes it does.

I give up on programing :( I"m going to study agriculture and build a farm or something...

Not in C++ compilers. In C, a function declared to take no parameters (void) is different from one without parameter declarations; in C++ this is not the case.
Where is your snake.cpp file?
The code that I downloaded does not have the implementation of CSnake.
The linker errors are valid.
