#include <iostream>

// so now, I can declare variables of type Complex_C

  // one advantage of objects from user defined classes, is that
  // I can write some code that gets automatically run everytime I declare
  // a new instance of that variable.
  // That function is the "constructor"... in this case, it will give
  // the c variable a value of "0" for the imaginary part, and "0" for the
  // real part.

  // We know that if I say "int x;" the value of x at that point is
  // whatever bits were left over in memory... the value is "junk bits"
  // the value is "arbitrary".

  cout << "c = ";
  c.print(); // calls the "print() member function" on object called "c"

  // I cannot say 
  //    cout << c;
  // unless I overload the << (stream insertion operator) for Complex_C;
  // we'll learn about that in Chapter 8.
