C++ New vs Malloc for dynamic memory array of Objects

Question

I have a class Bullet that takes several arguments for its construction. However, I am using a dynamic memory array to store them. I am using C++ so i want to conform to it's standard by using the new operator to allocate the memory. The problem is that the new operator is asking for the constructor arguments when I'm allocating the array, which I don't have at that time. I can accomplish this using malloc to get the right size then fill in form there, but that's not what i want to use :) any ideas?

pBulletArray = (Bullet*) malloc(iBulletArraySize * sizeof(Bullet)); // Works
pBulletArray = new Bullet[iBulletArraySize]; // Requires constructor arguments

Thanks.

You can't.

And if you truly want to conform to C++ standards, you should use std::vector.

FYI, it would probably be even more expensive than what you're trying to achieve. If you could do this, new would call a constructor. But since you'll modify the object later on anyway, the initial construction is useless.
