C++11 What is Delegating Constructors?
Delegating constructors are a feature introduced in C++11 that allows one constructor of a class to call another constructor of the same class to initialize the object. This feature simplifies code and eliminates the need to repeat the same code multiple times for different constructors. A delegating constructor has the same syntax as a regular constructor, but it calls another constructor of the same class in its member initializer list using the this keyword. Here's an example: class MyClass { public: MyClass(int x, int y) : x_(x), y_(y) {} MyClass(int x) : MyClass(x, 0) {} // delegating constructor private: int x_; int y_; }; In this example, the MyClass has two constructors: one that takes two int parameters and one that takes one int parameter. The second constructor is a delegating constructor because it calls the first constructor using this . The x parameter is passed to the first constructor, and the y parameter is set to zero.
