What are the advantages of operator overoloading in c plus plus?

Operator overloading allows you to redefine the functionality of most of the operators, such as + and -. This allows you to create a class that can naturally mimic a native object, such as an integer. Consider a complex number class. Clearly, you would want to overload the basic mathematical operations add, subtract, multiply, and divide, so that a user of your class code could write expressions involving complex numbers without having to think about the implementation details of your class. In the case of other types of classes, for instance a stack class, the meaning of the operators needs to be carefully considered, but it might make sense, for instance, to write a stack push operation as a unary plus, and a pop operation as a unary minus. Certainly, you don't want to go crazy overloading operators just because you can - you want the resulting code to be sensible and readable.
