I cannot compile because of one error.

My teacher gave me four files. Two header files and two *.cpp files. This is not the first time this format of assignment has been given and I did not have any problems in the past. This is an N-Queens puzzle. main.cpp asks the board size, switches to queen.cpp which I have to edit, essentially functions, etc. The first *.h file links the functions to the main, and the second *.h file is to identify myself. I barely edited the files. I simply added some missing headers like #include <iostream>, etc. and this error pops up no matter what I do. Thank you, help is appreciated!

 
  1>main.obj : error LNK2001: unresolved external symbol "public: void __thiscall Board::Solve(void)" (?Solve@Board@@QAEXXZ)


Should I post the entire 4 documents(given as is by my teacher)? They are approximately 20 lines each.
A linker error. Do you include both object files while linking?
Apparently, I have to implement the solve function. Thanks for the prompt reply keskiverto!
