2Overloaded Operators allow your classes to be used with things like +, -, /, [], and so forth. We typically use them with mathematical classes to have them act math-y, or we overload [] for array-like classes to make them array-y.
The Rule of Zero (which I usually follow) states that if you don't have any memory allocations or deallocations in your class, then you don't need a destructor, copy constructor, or assignment operator.
The Rule of Three (now the rule of Five, but w/e) states that if you do a allocation (such as new) in your constructor, you will need a destructor, a copy constructor, and an assignment (operator=) operator.
