They are equivalent. The int value is constant, cannot be modified. Now that you decalre a pointer to this type, this pointer can be set to any constant int value, but the pointer itself may be moved around freely among several constant integer values.

The difference comes when you move 'const' to the right of the asterisk:

int *const ptr = &xxx;

Now the xxx value may change, but ptr will always point to xxx. You are not allowed to move ptr to &yyy. You can consider *ptr as another way of writing xxx. Or ptr is another way of writing &xxx. You can't move xxx to refer to another variable either, so *ptr and xxx, or ptr and &xxx work the same way. You rarely need constant pointers; the address it is initialized with will serve the same purpose. But if the address expression is complex, and it is used many times, setting up a constant pointer may save both typing and improve readability (as long as a more descriptive name than "ptr" is chosen Smile | :) ).
