使用移动赋值从算术运算符重载返回常量值

#include <iostream>

class MyNumber {
private:
    int value;

public:
    MyNumber(int val) : value(val) {}

    // 移动赋值运算符重载
    const MyNumber& operator=(const MyNumber& other) {
        value = other.value;
        return *this;
    }

    // 算术运算符重载
    const MyNumber operator+(const MyNumber& other) const {
        int result = value + other.value;
        return MyNumber(result);
    }

    int getValue() const {
        return value;
    }
};

int main() {
    MyNumber num1(5);
    MyNumber num2(10);

    // 使用移动赋值运算符重载返回常量值
    const MyNumber result = num1 + num2;

    std::cout << "Result: " << result.getValue() << std::endl;

    return 0;
}
