In a C++ constructor do I have to allocate space for my instance fields (specifically I have two pointers as fields) or does calling “new” automatically allocate this space?

No. Instance fields of your classes are automatically allocated. If they are pointers, space is allocated for your pointers (4 bytes on 32 bit architectures, 8 bytes on 64 bit architectures). If you want your pointers to point to objects, you will need to either assign them or create objects for them to point to.
