使用參考
#include <iostream>
using namespace std;
struct Time{
int h;
int m;
int s;
};
void timeCompute(Time &t, int sec){ //參考作為形參
t.m = t.m + (t.s + sec)/60; //分鐘的進位
t.s = (t.s + sec)%60; //秒數位計算后剩余的時間
t.h = t.h + t.m/60; //小時的進位
t.m = t.m%60; //分鐘位計算后剩余的時間
t.h = t.h%24; //小時位取余實作24小時制
}
int main(){
int repeat,sec; //重復次數
cin >> repeat;
struct Time t; //創建一個time型別的結構體 t
for(int i = 0; i < repeat; i++){
scanf("%d:%d:%d", &t.h, &t.m, &t.s); //存入結構體 h m s
cin >> sec; //要度過的秒數
timeCompute(t,sec);
cout << t.h << ":" << t.m << ":" << t.s << endl;
}
return 0;
}
復雜且笨的寫法
