You made ValidWords a member variable which you are modifying in GetValidWords which means that can’t be a const member function.

@DanM

ember function.

I’m confused here.

error C2511: ‘TArray<FString,FDefaultAllocator> UBullCowCartridge::GetValidWords(TArray<FString,FDefaultAllocator>)’: overloaded member function not found in ‘UBullCowCartridge’

Your class definition has the following member function declared

TArray<FString> GetValidWords(TArray<FString>) const

But you have defined

TArray<FString> GetValidWords(TArray<FString>)
