I have been chasing my tail with this error.
My google needs a nap. Mr. Jeeves did not answer the door bell.
Here is BullCowCartridge.cpp

The errors I get are
argument of type “int32” is incompatible with parameter of type “int32 *”
and
declaration is incompatible with “void UBullCowCartridge::GetBullCows(const FString &Guess, int32 &BullCount, int32 *CowCount) const” (declared at line 22 of “C:\UNREAL PROJECTS\TUTORIALS\BULLCOWGAME-STARTER-KIT\SOURCE\BULLCOWGAME\BullCowCartridge.h”)
The first error is in regards to GetBullCows(Guess, Cows, Bulls);
I notice that if I change the order of (Guess, Cows, and Bulls) the red squiggle is always under the last variable.
e.g. Guess, Bulls, Cows)
The second error is saying the GetBullCows function declaration isnt compatible with the header.
This makes me think the first error is due to the second error.
Thank you for any insight. This course is the first time I have touched anything remotely close to programming. I don’t have the prerequisite knowledge to figure this out. If the answer is something super easy- please talk to me like I am a five year old.
