void FillUpTheBoard(int& pieces, char& GamePieces[]) 
etc...
void PrintedBoard(char& GamePieces[], int& pieces) 
etc...

You cannot have an array of references. This argument should be an array of char.

Remember, when you pass an array ot a function all you pass is the address of element 0. In this case the address of a char.

Fix these errors and most of the opthers will go away.

The one about an empty character literal means that when you use ' ' for a character literal, you need to put a character in there.
