title: C++ constructor call default constructor
body: <p>I have a problem calling the default constructor from other in c++. In Java was something like this:</p>
  
  <pre><code>class Book {
    static private int i;
    private String s;
  
    public Book() {
      i++;
    }
  
    public Book(String s) {
      this();
      this.s = s;
    }
  }
  </code></pre>
