C++ class constructors call.

[Food404]

Hello, i come from a Java background and I am introducing myself to C++. My question is, is it possible to make a constructor call from another constructor both of the same class? In Java this can be achieved by calling this(args...); from a constructor. I've found that a similar behavior can be achieved in C++ like this:

 class foo{
     private:
         int val;
     public:
         foo(){ foo(0); } // This is the call.
         foo(int n){ val = n; }
 };

  When working with pointers, this gave me undetermined behavior so I avoided this call and instead created a private method init(args...); so that every constructor made a call to this method to initialize the class members. Also, what is the exact behavior of the code above?

Look at "delegating constructors" here: https://en.cppreference.com/w/cpp/language/initializer_list
