添加代码重载+运算符实现两个计数器的相加 重载=运算符实现计数器的赋值

好的，以下是代码实现：

#include <iostream>
using namespace std;

class Counter {
private:
    int count;
public:
    Counter() : count(0) {}
    Counter(int c) : count(c) {}

    // 重载+运算符实现两个计数器的相加
    Counter operator+(const Counter& c) const {
        return Counter(count + c.count);
    }

    // 重载=运算符实现计数器的赋值
    Counter& operator=(const Counter& c) {
        count = c.count;
        return *this;
    }

    void display() const {
        cout << "Count: " << count << endl;
    }
};

int main() {
    Counter c1(5);
    Counter c2(10);
    Counter c3;

    // 测试重载+运算符
    c3 = c1 + c2;
    cout << "c1 + c2 = ";
    c3.display();

    // 测试重载=运算符
    c2 = c1;
    cout << "c2 = ";
    c2.display();

    return 0;
}

运行结果：

c1 + c2 = Count: 15
c2 = Count: 5
