Things to Remember in C++ Operator Overloading 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 ...

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 particular operators ...
Example The following example overloads the + operator to add two complex numbers and returns the result. C++ Copy // operator_overloading.cpp // compile with: /EHsc #include <iostream> using namespace std; struct Complex { Complex( double r, double i ) : re(r), im(i) {} Complex...
