Problem Statement |
|||||||||||||
| Computers tend to store dates and times as single numbers which represent the number of seconds or milliseconds since a particular date. Your task in this problem is to write a method whatTime, which takes an int,seconds, representing the number of seconds since midnight on some day, and returns a string formatted as "<H>:<M>:<S>". Here, <H> represents the number of complete hours since midnight, <M> represents the number of complete minutes since the last complete hour ended, and <S> represents the number of seconds since the last complete minute ended. Each of <H>, <M>, and <S> should be an integer, with no extra leading 0‘s. Thus, ifseconds is 0, you should return "0:0:0", while if seconds is 3661, you should return "1:1:1". | |||||||||||||

解析：
纯粹的秒数换算为时间的题目，只需要几个取模就可以了！
但是这是第一次用C++类来做题目，还是发现自己有很多不会的东西，就算是给自己学习添加动力吧！
而且，在topcoder上只需要将头文件和类提交，便可以了 所以主函数不用提交的！！！
代码：
#include <cstdio>
#include <cstdlib>
#include <iostream>
using namespace std;
class Time{
public:
string whatTime(int second){
int h = second/3600;
int m = second/60%60;
int s = second%60;
char str[64];
sprintf(str, "%d:%d:%d", h,m,s);
string ret = str;
return ret;
}
};
/*
int main(){
Time time;
int second;
cin >> second;
cout << time.whatTime(second) << endl;
return 0;
}
*/
