根据一个代表星期几的0到6之间的整数，在屏幕上输出它代表星期几

代码如下：

#include<iostream>using namespace std;int main(){    int w = 0;    cout << "请输入代表星期的数：" << endl;    while (1)    {        cin >> w;        switch (w)        {        case 0:            cout << "It's Sunday!" << endl;            break;        case 1:            cout << "It's Monday!" << endl;            break;        case 2:            cout << "It's Tuesday!" << endl;            break;        case 3:            cout << "It's Wednesday!" << endl;            break;        case 4:            cout << "It's Thursday!" << endl;            break;        case 5:            cout << "It's Friday!" << endl;            break;        case 6:            cout << "It's Saturday!" << endl;            break;        default:            cout << "请正确输入：" << endl;        }    }    system("pause");    return 0;}
