博客围绕加减运算符重载展开，但具体内容缺失。加减运算符重载是编程中重要操作，可让自定义类型使用加减运算，增强代码灵活性和可读性。

class Complex
{
public:
	Complex(int a, int b)
	{
		this->a = a;
		this->b = b;
	}
//操作符重载写在全局
	friend Complex operator+(Complex &c1, Complex &c2);
	friend Complex  operator-(Complex &c1, Complex &c2);
//操作符重载写在类里
	Complex operator+(Complex &another)
	{
		Complex temp(this->a + another.a, this->b + another.b);
		return temp;
	}
	Complex operator-(Complex &another)
	{
		Complex temp(this->a - another.a, this->b - another.b);
		return temp;
	}

private:
	int a;
	int b;
};

//操作符重载写在全局
Complex operator+(Complex &c1, Complex &c2)
{
	Complex temp(c1.a + c2.a, c1.b + c2.b);
	return temp;
}

Complex operator-(Complex &c1, Complex &c2)
{
	Complex temp(c1.a - c2.a, c1.b - c2.b);
	return temp;
}
