c++编写switch个人所得税代码

下面是C++编写switch个人所得税代码的范例：

#include <iostream>
using namespace std;

int main() {
    float x, z;
    int y;
    do {
        cout << "请输入月工资：";
        cin >> x;
        if (x <= 1800) {
            z = 0;
            cout << "个人所得税为：" << z << endl;
        } else {
            y = (x - 1800) / 1000;
            switch (y) {
                case 0:
                    z = (x - 1800) * 0.1;
                    cout << "个人所得税为：" << z << endl;
                    break;
                case 1:
                case 2:
                case 3:
                case 4:
                case 5:
                    z = 10000 * 0.1 + (x - 2800) * 0.15;
                    cout << "个人所得税为：" << z << endl;
                    break;
                default:
                    z = 10000 * 0.1 + 4000 * 0.15 + (x - 6800) * 0.2;
                    cout << "个人所得税为：" << z << endl;
                    break;
            }
        }
    } while (x > 0);
    return 0;
}
