Can you compare objects by address for equality?

Question

I have a function that compares objects by each attribute to see if they are identical. But I was just wondering, would it be better to compare the object by their address inste

Answer 1

If you have objects for which comparison is time consuming, comparing the pointers could be used as a fast way to determine object equivalence (i.e., if the pointers are equal, objects are equivalent, otherwise they may still be equivalent)
