I am making a trivia game that consist of 10 questions. I am using a class to make an array of 10 objects. I have the program all written out but when I compile I get two errors. Error 1 error LNK2019: unresolved external symbol "void __cdecl displayGame(class Game,int)" (?displayGame@@YAXVGame@@H@Z) referenced in function _main
The other error is Error 2 error LNK1120: 1 unresolved externals
Does anybody have a clue what can be causing the errors? Thanks in advance!
