2. wenn in C++ nur referenz zum einsatz kommt, wieso benutzt man immer noch pointer in C -style?
class Complex{
double real;
double im;
Bruch(double r, double i):real(r), im(i){}
}
Complex c(1.5, 2);
Complex add(Complex c);
Complex result = c.add(c);
Complex& add(Complex& c);
Complex result = c.add(c);
