重载+号运算符！

[大道如海]

我在做一个复数的实例时，用到+号运算符的重载.
我试着写了一个，可以运行，但不知道符不符合运算符重载的规则，或者说下面的写法有没有不妥的地方。如果有，如何改正。
Complex Complex::operator+(Complex right)
{
realPart += right.realPart ;
imaginaryPart += right.imaginaryPart ;

return *this;
}

realPart,imaginaryPart为代表实部和虚部的成员变量。

msdn 有例子:

// operator_overloading.cpp
// compile with: /EHsc
#include <iostream>

using namespace std;
class Complex
{
public:
Complex( double r, double i ) : re(r), im(i) {}
Complex operator+( Complex &other );
void Display( ) { cout << re << ", " << im << endl; }
private:
double re, im;
};

// Operator overloaded using a member function
Complex Complex::operator+( Complex &other )
{
return Complex( re + other.re, im + other.im );
}

void main()
{
Complex a = Complex( 1.2, 3.4 );
Complex b = Complex( 5.6, 7.8 );
Complex c = Complex( 0.0, 0.0 );

c = a + b;
c.Display();
}

Complex& Complex::operator+(Complex const &right)
{
realPart += right.realPart ;
imaginaryPart += right.imaginaryPart ;

return this;
}

sorry,上面写错了：呵呵，

Complex Complex::operator+(Complex const &right)
{
realPart += right.realPart ;
imaginaryPart += right.imaginaryPart ;

return this;
}

TO:xieha(右边的话是正确的，左边的话是错误的)
似乎return this这句话有问题。

no problem!

[meteor135]

Complex Complex::operator+(Complex const &right)
{
realPart += right.realPart ;
imaginaryPart += right.imaginaryPart ;

return this; //这里对吗？this可是指针哦！改成return *this;
}
