operator new without implementation?

[LarryChen]

Here is the code,

class A
{
private:
	void* operator new(size_t size);
};

int main()
{
    return 0;
}

The code above compiles fine without errors. But operator new might not have implemenation body? Thanks.

Try to create instance of class A.

Your example is really no different to

class A
{
private:
	void* someFunction();
};

int main()
{
    return 0;
}

If you don't try to call someFunction, or new in your case, there is no problem.

Do you work with C++ or do you just sit around trying to come up with crazy questions?
