In C++, We can have more than one constructor in a class with same name, as long as each has a different list of arguments.This concept is known as Constructor Overloading and is quite similar to function overl

An explicit destructor which guarantee that a queue would be empty when it expires A copy constructor and overloading the assignment operator is also required, but you could escape this now: classQueue{private: Queue(constQueue & q) : qsize(0) { } Queue &operator=(constQueue & q) {retu...
To accomplish initialization while declaration for class objects, C++ provides special member functions calledclass constructors. In fact,a constructor has no return type, its name is often same to the class's name. For example: constructor for class Stock is Stock() 10.3.1 Declaring and definin...
from non-ADL lookup friend X operator+(X lhs, // passing lhs by value helps optimize chained a+b+c const X& rhs) // otherwise, both parameters may be const references { lhs += rhs; // reuse compound assignment return lhs; // return the result by value (uses move constructor) } ...
In the lesson onoverloading the subscript operator, you learned that we could overload operator[] to provide direct access to a private one-dimensional array. However, in this case, we want access to a private two-dimensional array. Prior to C++23, operator[] is limited to a single param...

C++0x introduces a new mechanism called “rvalue reference” which, among other things, allows us to detect rvalue arguments via function overloading. All we have to do is write a constructor with an rvalue reference parameter. Inside that constructor we can do anything we want with the sou...
(const Mat&) = delete; // delete the copy constructor Mat& operator=(const Mat&) = delete; //delete the assignment operator overloading T getElement(size_t r, size_t c); bool setElement(size_t r, size_t c, T value); }; // Function template template <typename T> T Mat<T>:...
Added a constructor accepting a status code and a r-value returnable. This is convenient so we can return custom returnables along with a status code without having to create an l-value first like this: classApiResponse:publiccrow::returnable ...
