Thread: What are these numbers?

I have the following function, when it is called, it printed out two sets of numbers 0x3d2468 and 0x3d2590. What are these numbers represent? What are they used for? Thanks in advance.

Code:

typedef int* ptrType;

int somefunction()
{
    ptrType P = new int;
    ptrType Q = new int;
    cout << P <<" " << Q <<endl;
    return 0;
}
