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. ...
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 ...
Unary operators The following example shows the syntax to overload all the unary operators, in the form of both global functions (non-member friend functions) and as member functions. These will expand upon the Integer class shown previously and add a new byte class. The meaning of your parti...
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. ...
cout << "\t" << pos1.x << " + " << pos1.y << " = " << pos1.x + pos1.y << std::endl; } void Example_2(Position_2 pos1, Position_2 pos2 ){ Position_2 new_pos = pos1 + pos2; // Correct way: overload Position operator /* What does this operation means and ...

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...
