一、

#include<iostream>
using namespace std;
void PrintfDay(int y, int m, int d); //声明PrintfDay函数  

//年大于等于0
//月大于等于1，小于等于12
//日大于等于1-31

        int day = days[month];
        if ((year % 4 == 0 && year % 100 != 0) || ((year % 400 == 0) && month == 2))
        {
            day += 1;
        }
        return day;
    }
    void Caculate(int y, int m, int d) {
        int Week = (d + 2 * m + 3 * (m + 1) / 5 + y + y / 4 - y / 100 + y / 400) % 7;
        switch (Week)
        {
        case 0: PrintfDay(y, m, d); cout << "是星期一" << endl; break;

        }
    }
    void Setday(int year, int month, int day)
    {
        if (year >= 1900 && month > 0 && month < 13 && day>0 && day <= JudgeWeekDay(year, month))

        }
    }
    void PrintfDay(int y, int m, int d)
    {
        if (m == 13 || m == 14) //把一月和二月换算成上一年的十三月和十四月  
        {
            m -= 12;
            y++;
        }
        cout << y << "年" << m << "月" << d << "日";
    }
private:

};
int main()
{
    date date1;
    int year, month, day;
    cout << "请输入年 月 日" << endl;
    cin >> year >> month >> day;
    date1.Setday(year, month, day);
    return 0;
}

二、

#include<iostream>
using namespace std;
void zhaoling(int n) {
    int n50, n10, n5, n1;
    int s = n - 50;
    if (s == 0) {
        cout << "刚好购买，不需找零！";
        exit(0);
    }
    n50 = (int)s / 50;
    s = s - (n50 * 50);
    n10 = (int)s / 10;
    s = s - (n10 * 10);
    n5 = (int)s / 5;
    s = s - (n5 * 5);
    n1 = s;
    cout << "找回零钱" << n - 50 << "元，其中五十元" << n50 << "张，10元" << n10 << "张，5元" << n5 << "张，1元" << n1 << "张" << endl;

}
int main() {
    int pay;
    cout << "请输入金额:" << endl;
    cin >> pay;
    if (pay <= 0 || pay > 100) {
        cout << "输入金额不正确！！！";
    }
    else if (pay < 50) {
        cout << "金额不足！！！";
    }
    else {
        zhaoling(pay);
    }
}

三、

#include<iostream>
using namespace std;
void main() {
    int m, n;
    cout << "请投币：1、一元；2、五角" << endl;
    cin >> n;
    if (n == 1) {
        cout << "请选择商品：1、啤酒；2、橙汁" << endl;
        cin >> m;
        if (m == 1) {
            cout << "请取啤酒" << endl;
            cout << "找零五角！" << endl;
        }
        if (m == 2) {
            cout << "请取橙汁" << endl;
            cout << "找零五角！" << endl;
        }
        exit(0);
    }
    if (n == 2) {
        cout << "请选择商品：1、啤酒；2、橙汁" << endl;
        cin >> m;
        if (m == 1) {
            cout << "请取啤酒" << endl;
        }
        if (m == 2) {
            cout << "请取橙汁" << endl;
        }
        exit(0);
    }
}

四、

#include<iostream>
using namespace std;
int main() {
    int hxian,cwei, fxsjian;
    cout << "请输入航线：1、欧美；2、国外非欧美；3、国内" << endl;
    cin >> hxian;
    cout << "请输入舱位：1、经济舱；2、商务舱" << endl;
    cin >> cwei;
    cout << "请输入飞行时间：1、两小时以内；2、超过两小时" << endl;
    cin >> fxsjian;
    cout << "该次航班服务有：" << endl;
    if (hxian == 1) {
        cout << "每个座位都有食物供应，每个座位都可以放电影。" << endl;
    }
    if (hxian == 2) {
        cout << "每个座位有食物供应" << endl;
        if (cwei == 2) {
            cout << "可以播放电影" << endl;
        }
    }
    if (hxian == 3) {
        if (cwei == 1) {
            if (fxsjian == 1)
                cout << "无" << endl;
            if (fxsjian == 2)
                cout << "食物供应" << endl;
        }
        if (cwei == 2) {
            cout << "食物供应" << endl;
        }
    }
    return 0;
}
