title: Proper way to accomplish this construction using constructor chaining?
body: <p>I have an assignment for my first OOP class, and I understand all of it including the following statement:</p>
  
  <blockquote>
    <p>You should create a class called ComplexNumber. This class will contain the real and imaginary parts of the complex number in private data members defined as doubles. Your class should contain a constructor that allows the data members of the imaginary number to be specified as parameters of the constructor. A default (non-parameterized) constructor should initialize the data members to 0.0.</p>
  </blockquote>
  
  <p>Of course I know how to create these constructors without chaining them together, and the assignment does not require chaining them, but I want to as I just like to.</p>
  
  <p>Without chaining them together, my constructors look like this: </p>
  
  <pre><code>class ComplexNumber
  {
      private double realPart;
      private double complexPart;
  
      public ComplexNumber()
      {
           realPart = 0.0;
           complexPart = 0.0
      }
  
      public ComplexNumber(double r, double c)
      {
           realPart = r;
           complexPart = c;
      }
      // the rest of my class code...
  }
  </code></pre>
