C++ call constructor from another constructor

In C# it is not possible to call another constructor from inside the method body. You can call a base constructor this way: foo(args):base() as pointed out yourself. You can also call another constructor in the same class: foo(args):this() .

Call One Constructor From Another Within the Same Class in Java. When we want to call one constructor from another constructor within the same class, we use the this keyword . An expression that uses the this keyword must be the first line of the constructor. The order doesn’t matter in the constructor chaining.

Constructor chaining is the process of calling one constructor from another constructor with respect to current object . Constructor chaining can be done in two ways: Within same class: It can be done using this() keyword for constructors in same class.

The invocation of one constructor from another constructor within the same class or different class is known as constructor chaining in Java. If we have to call a constructor within the same class, we use ‘this’ keyword and if we want to call it from another class we use the ‘super’ keyword.
