求下一秒对应的日期

2013-07-28 21:46:31

输入年、月、日、时、分、秒，输出下一秒的年、月、日、时、分、秒。

注意点：

1. 加上输入合法性检查，在下面的代码中没有加；
2. 注意闰年的情况；

代码：

#include <iostream>
using namespace std;

size_t MonthTable[2][12] = { {31,29,31,30, 31,30,31,31, 30,31,30,31},
                             {31,29831,30, 31,30,31,31, 30,31,30,31} };

typedef struct data
{
    size_t year;
    size_t month;
    size_t day;
    size_t hour;
    size_t minute;
    size_t second;
}Data;

bool IsLeapYear(const size_t year)
{
    return ( (year % 4 == 0 && year % 100 != 0 ) || (year % 400 == 0 ) );
}

void GetNextDay(Data &currentDate,Data &nextDate)
{
    size_t maxDayInMonth = MonthTable[ ( IsLeapYear(currentDate.year) )][currentDate.month - 1];


    nextDate.day = (currentDate.day + 1) % maxDayInMonth;

    if (0 == nextDate.day)
    {
        nextDate.day = maxDayInMonth;
    }
    
    if (1 == nextDate.day)
    {
        nextDate.month = (currentDate.month + 1) % 12;

        if (0 == nextDate.month)
        {
            nextDate.month = 12;
        }

        if (1 == nextDate.month)
        {
            nextDate.year += 1;
        }
    }
}

void DateCopy(const Data &currentDate,Data &nextDate)
{
    nextDate.year = currentDate.year;
    nextDate.month = currentDate.month;
    nextDate.day = currentDate.day;
    nextDate.hour = currentDate.hour;
    nextDate.minute = currentDate.minute;
    nextDate.second = currentDate.second;
}

void GetNextSecond(Data &currentDate,Data &nextDate)
{
    DateCopy(currentDate,nextDate);
    nextDate.second = (currentDate.second + 1) % 60;
    if (0 == nextDate.second)
    {
        nextDate.minute = (currentDate.minute + 1) % 60;
        if (0 == nextDate.minute)
        {
            nextDate.hour = (currentDate.hour + 1) % 24;

            if (0 == nextDate.hour)
            {
                GetNextDay(currentDate,nextDate);
            }
        }
    }
}

void TestDriver()
{
    Data currentDate;
    Data nextDate;

    cout<<"please enter a data(year month day hour minute second),end with ctrl+z"<<endl;

    while (cin>>currentDate.year>>currentDate.month>>currentDate.day
        >>currentDate.hour>>currentDate.minute>>currentDate.second)
    {
        cout<<"the date of the current second is: "<<currentDate.year<<"	"<<currentDate.month<<"	"<<currentDate.day<<"	"<<
            currentDate.hour<<"	"<<currentDate.minute<<"	"<<currentDate.second<<endl;
        GetNextSecond(currentDate,nextDate);
        cout<<"the date of the next second is: "<<nextDate.year<<"	"<<nextDate.month<<"	"<<nextDate.day<<"	"<<
            nextDate.hour<<"	"<<nextDate.minute<<"	"<<nextDate.second<<endl;
        cout<<"please enter a data(year month day hour minute second),end with ctrl+z"<<endl;
    }
}

int main()
{
    TestDriver();
    return 0;
}

运行结果：
