C++编写程序，使用switch语句，将输入的数字（1-7）转换成对应的星期英文名称输出

在C++中，你可以使用`switch`语句结合`enum`来实现这个功能。首先，你需要创建一个枚举类型，表示一周的天数，然后通过输入值匹配相应的字符串。以下是示例代码：

#include <iostream>
using namespace std;

enum class WeekDays {
    Monday = 1,
    Tuesday,
    Wednesday,
    Thursday,
    Friday,
    Saturday,
    Sunday
};

 WeekDays getDayOfWeek(int input) {
    switch (input) {
        case 1:
            return WeekDays::Monday;
        case 2:
            return WeekDays::Tuesday;
        case 3:
            return WeekDays::Wednesday;
        case 4:
            return WeekDays::Thursday;
        case 5:
            return WeekDays::Friday;
        case 6:
            return WeekDays::Saturday;
        case 7:
            return WeekDays::Sunday;
        default:
            cout << "Invalid input! Please enter a number between 1 and 7." << endl;
            return WeekDays::Monday; // 返回默认的第一天，以处理无效输入
    }
}

int main() {
    int userInput;
    cout << "Enter a number between 1 and 7 to represent the week day: ";
    cin >> userInput;

    WeekDays day = getDayOfWeek(userInput);
    cout << "The corresponding day is: " << static_cast<string>(day) << endl; // 转换枚举为字符串输出

    return 0;
}
