Suppose you want to add a constructor to Complex that takes a double value as its argument and creates a Complex number with that value as the real part (and no imaginary part). You write the following code:

public void Complex(double real){   re = real;   im = 0.0;}

But then the statement Complex c = new Complex (1.0) does not compile. Why?
