Hey!
Also hab ein Programm geschriebn und da kommt ein Fehler den ich irgendwie nicht finden kann.. :/
| C++: |
//complex.h
#ifndef _COMPLEX_
#define _COMPLEX_
#include <iostream>
class Complex
{
private:
double a,b;
public:
Complex();
Complex(double,double);
Complex(Complex &);
~Complex();
double getA() { return a; }
double getB() { return b; }
friend Complex operator +(Complex const &a, Complex const &b);
friend Complex operator *(Complex const &a, Complex const &b);
Complex operator +=(Complex const &b);
};
std::ostream &operator <<(std::ostream &o, Complex &a);
#endif
|
| C++: |
//complex.cpp
#include <iostream>
#include "complex.h"
using namespace std;
Complex::Complex() : a(0), b(0) { }
Complex::Complex(double x, double y) : a(x), b(y) { }
Complex::Complex(Complex &x) : a(x.a), b(x.b) { }
Complex::~Complex() { }
Complex operator +(Complex const &a, Complex const &b)
{
Complex c;
c.a = a.a + b.a;
c.b = a.b + b.b;
return c;
}
Complex operator *(Complex const &a, Complex const &b)
{
Complex c;
c.a = a.a * b.a;
c.b = a.b * b.b;
return c;
}
Complex Complex::operator +=(Complex const &b)
{
Complex c;
c.a = c.a + b.a;
c.b = c.b + b.b;
return c;
}
std::ostream &operator <<(std::ostream &o, Complex &a)
{
o << a.getA() << "+" << a.getB() << "*i" << endl;
return o;
}
|
| C++: |
// main.cpp
#include <iostream>
#include "complex.h"
using namespace std;
int main()
{
Complex a;
Complex b(3.5333,22.52552);
Complex c(b);
cout << "b + c = " << b+c << endl;
cout << "b = b + c = " << b+=c << endl;
cout << "b * c = " << b*c << endl;
return 0;
}
|
Da kommt der Fehler:
error C2678: binary '<<' : no operator defined which takes a left-hand operand of type 'class Complex' (or there is no acceptable conversion)
Jo ich hab immer und immer wieder diese Fehler und hab keine Ahnung woran das liegen kann... ???
