For up-to-date information on C++, see the main reference at cppreference.com. Operator overloading in C++ allows us to write natural expressions like d = a + b / c; with our own classes. The above expression could be equal to d = a.add(b.divide(c)); which results in hard ...
There are no specific downsides to overloading this operator, but it is rarely used in practice. It was suggested that it could be part of a smart pointer interface, and in fact is used in that capacity by actors in boost.phoenix. It is more common in EDSLs such as cpp.react. ...

1. By default, operators=and&are already overloaded in C++. For example, we can directly use the=operator to copy objects of the same class. Here, we do not need to create an operator function. 2. We cannot change the precedence and associativity of operators using operator overloading. ...

In this section See also Theoperatorkeyword declares a function specifying whatoperator-symbolmeans when applied to instances of a class. This gives the operator more than one meaning, or "overloads" it. The compiler distinguishes between the different meanings of an operator by examining the type...

http://www.cs.caltech.edu/courses/cs11/material/cpp/donnie/cpp-ops.html 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 calledoperator overloading. You can implement C++ operator overloads by provid...
