一个判断你活了多少天的程序

这2天看到一个关于计算你一共活了多少天的题目,看了之后写了下代码,感觉要珍惜生命了,呵呵 代码如下:

 

#include<iostream>
using namespace std;

struct Date
{
    int nYear;
    int nMouth;
    int nDay;
};

bool JudYear(int nYear)
{
    if( (nYear % 4 ==0 && nYear % 100 !=0) || nYear % 400 ==0)
    {
        return true;
    }
    else
    {
        return false;
    }
    
}

bool CheckDate( Date *p)

{
    int aDay[] = {0,31,28,31,30,31,30,31,31,30,31,30,31};
    int aDay2[] = {0,31,29,31,30,31,30,31,31,30,31,30,31};

    if ( (p ->nDay) >31 || (p ->nDay) <1 || (p -> nMouth) >12 || (p -> nMouth) <1 || (p -> nYear) <1)

    {
        return false;
    }

        bool isLeapYear = JudYear( (p ->nYear));

        if (isLeapYear)

        {

            if ( (p ->nDay) > aDay2[(p ->nMouth)])

            {

                return false;

            }

        }

        else

        {

            if ( (p ->nDay) > aDay[(p ->nMouth)])

            {

                return false;

            }

        }



}

//获得现在年到生日年一共多少天

int GetYear(int nBeforYear,int nCurreYear)
{
        int nSum = 0;
        int nNum = ( nCurreYear - nBeforYear ) * 365;
        for ( nBeforYear;nBeforYear < nCurreYear;nBeforYear++)
        {
            if ( JudYear(nBeforYear) )
            {
                    nSum += 1;
            }
            else
            {
                nSum = nSum;
            }
        }

        return ( nSum + nNum ) ;
}

//获取生日月份是一年中的多少天数

int GetBeforMouth(int nBeforMouth)
{
    int aDay[] = {0,31,28,31,30,31,30,31,31,30,31,30,31};
    int aDay2[] = {0,31,29,31,30,31,30,31,31,30,31,30,31};
    int nSum = 0;
    if ( JudYear(nBeforMouth) )
    {
        for ( int i = 1; i < nBeforMouth;i++)
        {
            nSum += aDay2[i];
        }
    }
    else
    {
        for ( int i = 1; i < nBeforMouth;i++)
        {
            nSum += aDay2[i];
        }
    }
    return nSum;

}


int main()
{
    Date BeforDate = {0};
    Date NowDate = {0};
    int nYear = 0;
    int nSum = 0;
    cout<<"请输入你的生日,请按年月日来进行输入"<<endl;
    cin>>BeforDate.nYear>>BeforDate.nMouth>>BeforDate.nDay;
    if ( ! CheckDate( &BeforDate) )
    {
        cout<<"输入日期有错误"<<endl;
    }
    cout<<"请输入当前的时间,请按年月日来进行输入"<<endl;
    cin>>NowDate.nYear>>NowDate.nMouth>>NowDate.nDay;
    if ( ! CheckDate( &NowDate ) )
    {
        cout<<"输入日期有错误"<<endl;
    }
    
    cout<<endl;
    nYear = GetYear(BeforDate.nYear,NowDate.nYear);
    nSum = nYear - GetBeforMouth(BeforDate.nMouth) + GetBeforMouth(NowDate.nMouth) - BeforDate.nDay + NowDate.nDay;
    cout<<"一共活了"<<nSum<<"天"<<endl;

    return 0;
}
