c++用switch写利润提成

以下是使用C++的switch语句来计算利润提成的代码：

#include <iostream>
using namespace std;

int main() {
    double I, bonus;
    cout << "请输入当年利润I：";
    cin >> I;

    switch ((int)I / 100000) {
        case 0:
            bonus = I * 0.1;
            break;
        case 1:
            bonus = 10000 + (I - 100000) * 0.075;
            break;
        case 2:
        case 3:
            bonus = 17500 + (I - 200000) * 0.05;            break;
        case 4:
        case 5:
        case 6:
        case 7:
        case 8:
        case 9:
            bonus = 27500 + (I - 400000) * 0.03;
            break;
        default:
            bonus = 65500 + (I - 1000000) * 0.01;
            break;
    }

    cout << "应发放奖金总数为：" << bonus << "元" << endl;

    return 0;
}
