C++ class initialization with and without parentheses [duplicate]

Question

What is the difference between the following 2 two initializations?

class Pod {
public:
    int a, b;
};

Pod *p1 = new Pod;
Pod *p2 = new Pod();

Answer 1

In the first case the object is left uninitialized, while in the second case the object is guaranteed to be value-initialized, which in this case as the type is POD it means zero-initialized
