When a user-defined class overloads the function call operator operator(), it becomes a FunctionObject type. An object of such a type can be used in a function call expression: // An object of this type represents a linear function of one variable a * x + b. struct Linear { ...
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 ...
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...
