How to Random integer in Range? C++

Alexa.Ki · August 4, 2022, 4:36am

in my case i have

ReturnRandomNumber(int32& Number) //By ref ? and should be (int32 Number) to make it //Getting a copy ?
 {
    TArray<int32> Arr{};
    Number = Arr[FMath::RandRange(0, 99)];  // Number is By ref returning the output?
 }

maybe this way is correct?

ReturnRandomNumber(int32& Number) 
 {
    TArray<int32> Arr{};
    int32 ByCopy = Arr[FMath::RandRange(0, 99)];
    Number = ByCopy;
 }
