Question

Lets say I have a class A and I overload operator new in the class.

class A{
    public:
    A();
    void *operator new(size_t size);
    void operator delete(void *p);
}

How would I use this overloaded operator new inside of class A instead of the global new?
For example

A::A(){
    ...
    int *temp = new int[10];  //Use overloaded new and not global new
}

I looked around and I don’t think I saw a question that addressed this.

Thanks!

That overloaded version will be used for creating objects of class A and its descendants only – such as when you have new A() in your code. It won’t be called for new A[] unless you overload operator new[]() as well.

In order to have your operator new[]() function used when you do new int[] you have to replace global operator new()[] function.
