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 ...
classComplex{…..public: Complexoperator+ (constComplex& obj){ Complex temp; temp.real = real + obj.real; temp.img = img + obj.img;returntemp; } ……. }; In this case, the operator is invoked by the first operand. Meaning, the line ...
http://www.cpp.sh/ Operators Overloading in C++ Box operator+(const Box&); Box operator+(const Box&, const Box&);Following is the example to show the concept of operator over loading using a member function. Here an object is passed as an argument whose properties will be accessed ...
When an operator appears in an expression, and at least one of its operands has a class type or an enumeration type, then overload resolution is used to determine the user-defined function to be called among all the functions whose signatures match the following: ...
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...
