A pointer is a type of variable that carries location information. In this case, the example variable will store the address of an Order object that we want to interact with. We initialize the pointer variable by using the C++ new operator to construct a new object of type Order.
It doesn't point to anything. There is nothing useful you can do with its value now. Save this answer.
To assign a pointer to the array we can use the following declaration... int a[10]; int *pa = &a[0]; Basically this assigns the memory address of a[0] the first element in array a to pointer of type int .
In C++ Primer, Chapter 2, "Variables and Basic Types", it says:
it is possible for a pointer to an object and a pointer one past the end of a different object to hold the same address.
I'm not a native speaker, and I think that's why I'm a bit confused by the sentence "a pointer one past the end of an object". Would anyone one tell me what it means please?
