== 代码示例：复数类的加法运算 ==
以下是一个完整的示例，展示如何重载<code>+</code>运算符来实现复数的加法：

<syntaxhighlight lang="cpp">
#include <iostream>

class Complex {
private:
    double real;
    double imag;

public:
    Complex(double r = 0.0, double i = 0.0) : real(r), imag(i) {}

    // 成员函数形式的运算符重载
    Complex operator+(const Complex& other) const {
        return Complex(real + other.real, imag + other.imag);
    }

    void display() const {
        std::cout << real << " + " << imag << "i" << std::endl;
    }
};

int main() {
    Complex c1(3.0, 4.0);
    Complex c2(1.0, 2.0);
    Complex c3 = c1 + c2; // 使用重载的+运算符

    c3.display(); // 输出: 4 + 6i
    return 0;
}
</syntaxhighlight>

'''输出:'''
<pre>
4 + 6i
</pre>
