Besides, operator overloading is just syntactic sugar for function calls. Although this particular syntactic sugar can be very sweet, it doesn't add anything fundamental.

Operator overloading is the ability to tell the compiler how to perform a certain operation when its corresponding operator is used on one or more variables. For example, the compiler acts differently with regards to the subtraction operator “-“ depending on how the operator is being used.

One of the nice features of C++ is that you can give special meanings to operators, when they are used with user-defined classes. This is called operator overloading. You can implement C++ operator overloads by providing special member-functions on your classes that follow a particular naming convention.

The operators can be programmed to do whatever we want them to. However, some words of caution. Operator overloading provides NO additional functionality to your code. It just compiles to normal function calls. It's even written out like normal function calls.

For example, overloading the [] operator for a data structure allows x = v[25] in place of a function call. This is purely a conveniece to the user of a class. Operator overloading isn't strictly necessary unless other classes or functions expect operators to be defined (as is sometimes the case).
