Default Member Functions Default member functions are those implicitly generated by the compiler when a class does not explicitly define them. For an empty class, the compiler creates six default members, with the first four being essential: constructor, destructor, copy constructor, and assignment...
During copy initialization (using the equals sign), compilers may bypass copy or move constructors and create objects directly. This optimizatino is permitted but not required by the standard. std::string book_id = "123"; // Can be rewritten as: std::string book_id("123"); In thi...
After covering destructors in a previous note, this antry continues with two essential default member functions: copy constructors and operator overloading. Copy Constructor A copy constructor is a special constructor whose first parameter is a reference to the same class type, and any additional pa...
