Complex class problem

[hannes]

hi,

I'm making my own base c++ classes to use in couple of applications. Now, i'm working on my own Complex class for managing complex numbers, but there is something wrong. Here is my code:

/*
 * main.cpp
 *
 *  Created on: 6-okt-2010
 *      Author: Hannes
 */
#include "complex.h"
#include <iostream>

using namespace math;

int main( ) {
	Complex a;
	a.set_all( 1, 2 );
	Complex b = a;
	std::cout<<b.get_imag()<<std::endl;
	return 0;
}

/*
 * complex.h
 *
 *  Created on: 6-okt-2010
 *      Author: Hannes
 */

#ifndef COMPLEX_H_
#define COMPLEX_H_

namespace math {

	class Complex {
	private:
		double re, im;

	public:
		Complex( double = 0, double= 0 );
		Complex( const Complex& );
		virtual ~Complex( void );

		double get_real( void );						//return real part of complex number
		double get_imag( void );						//return imaginary part of complex number
		void set_all( double = 0, double = 0  );		//set real and imaginary part, default 0
		void set_real( double = 0 );					//set real part of complex, default 0
		void set_imag( double = 0 );					//set imaginary part of complex, default 0
	};

};

#endif /* COMPLEX_H_ */ 

/*
 * complex.cpp
 *
 *  Created on: 6-okt-2010
 *      Author: Hannes
 */

#include "complex.h"
#include <iostream>

namespace math {
	Complex::Complex( double real , double imag ) {
		set_all( real, imag );
	}

	Complex::Complex( const Complex& c ){
		set_all( c.re, c.im );
	}

	Complex::~Complex( void ) {
		delete &re;
		delete &im;
		delete this;
	}

	double Complex::get_imag( void ) {
		return im;
	}

	double Complex::get_real( void ) {
		return re;
	}

	void Complex::set_all( double real , double imag  ){
		re = real;
		im = imag;
	}

	void Complex::set_real( double real  ) {
		re = real;
	}

	void Complex::set_imag( double imag  ) {
		im = imag;
	}

}

There error comes up at the end, after printing the imaginary part of b.

delete lines 21, 22, and 23. for that matter, delete the whole destructor; you don't need it.
