Question

I am making some game and I get following error :

class Apple:public Fruit{
public:
    bool isAppleOK = false;
Apple(int amount, int pHValue) {
    amount = amount;
    pHValue= pHValue;
} ~Apple() {
}
    /*code trimmed*/

error C2864: ‘Apple::isAppleOK ‘ : only static const integral data members can be initialized within a class

What am I missing here?

Answer 1

This is not the way you initialize member variables in C++. You need to set the value in the init list of the constructor:

Apple(int amount, int pHValue) : isAppleOK(false) {
    amount = amount;
    pHValue= pHValue;
}

You can also move the initialization of your other variables into the initialization list:

Apple(int amt, int pHv)
:   isAppleOK(false)
,   amount(amt)
,   pHValue(pHv) {
}
