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 { ...
When look into the above snapshot,it had invoked the overloaded assignment method and print the identical information. But to my surprise,their addresses are different as below,think further,because they are different objects and called constructor respectively....
// assignment operator, generated by compiler Complex<T>& operator=(Complex<T> const& other) = default; // addition Complex<T> operator+(Complex<T> const& rhs) const; // this could be a template method with any Complex<S> convertible to Complex<T> Complex<T>& operator+=(Complex<T>...

Operator() is sometimes overloaded with two parameters to index multidimensional arrays, or to retrieve a subset of a one dimensional array (with the two parameters defining the subset to return). Anything else is probably better written as a member function with a more descriptive name. ...
Overloading the multiplication operator (*) and the division operator (/) is as easy as defining functions for operator* and operator/ respectively. Friend functions can be defined inside the class Even though friend functions are not members of the class, they can still be defined inside the...

First, we encapsulate a raw pointer and overload the operators -> and *, so our class feels like a pointer: template<typename T> class unique_ptr { T* ptr; public: T* operator->() const { return ptr; } T& operator*() const { return *ptr; } The constructor takes ownership of ...
