这道题不需要对time.minutes进行取模运算，因为题目已经说了，minutes < 59 ，所以两个时间相加最大不会超过128，也就是说minutes最多减60，hours最多加1。

#include <iostream>
using namespace std;

class Time {

    public:
        int hours;      // 小时
        int minutes;    // 分钟

        Time() {
            hours = 0;
            minutes = 0;
        }

        Time(int h, int m) {
            this->hours = h;
            this->minutes = m;
        }

        void show() {
            cout << hours << " " << minutes << endl;
        }

        // write your code here......
        
};
Time operator+(Time &t1, Time &t2)
        {
            Time time;
            time.hours = t1.hours + t2.hours;
            time.minutes = t1.minutes + t2.minutes;
            if(time.minutes >= 60) 
            {
                time.minutes -= 60;
                time.hours += 1;
            }
            return time;
        }

int main() {

    int h, m;
    cin >> h;
    cin >> m;

    Time t1(h, m);
    Time t2(2, 20);

    Time t3 = t1 + t2;
    t3.show();
    
    return 0;
}
