Why is FString not used as a pointer, like in the Output function

Why is it correct to use it without pointer:
void UBullCowCartridge::ProcessGuess(FString Guess)
I would think you should use it like this, because the string variable Guess is a pointer:
void UBullCowCartridge::ProcessGuess(const FString& Guess)

It’s not a pointer. In a declaration & means reference not address-of. References are covered later in the course and ProcessGuess will be changed to use a reference.
