将秒转换为天，小时，分钟，秒。

第一感觉，想到的最笨方法。哈哈。

#include <iostream>#include <climits>using namespace std;int main(){        long long time = 0;    cout << "Input the total seconds:" << endl;    cin >> time;    long long day = time / 86400;    long long hour = (time - day*86400) / 3600;    long long minute = (time - day*86400 - hour*3600) / 60;    long long second = (time - day*86400 - hour*3600 - minute * 60);    cout << time << " seconds = " << day << " days " << hour << " hours " << minute << " minutes " << second << " seconds.";    return 0;}

不解释拉哈。
