优惠购物c++ switch

根据引用和引用提供的信息，可以使用switch语句编写一个关于商场购物金额优惠的程序。根据顾客购物小票上的消费金额，程序会输出顾客将享受的折扣与打折后需支付的金额。

#include <iostream>
using namespace std;

int main() {
    double x;
    cin >> x;
    
    int y;
    y = x / 500;
    
    switch(y) {
        case 0:
            cout << "discount: " << "No discount! " << "price: " << x << endl;
            break;
        case 1:
            cout << "discount: " << "9 " << "price: " << 0.9 * x << endl;
            break;
        case 2:
        case 3:
            cout << "discount: " << "8 " << "price: " << 0.8 * x << endl;
            break;
        case 4:
        case 5:
            cout << "discount: " << "7 " << "price: " << 0.7 * x << endl;
            break;
        case 6:
        case 7:
        case 8:
        case 9:
            cout << "discount: " << "6 " << "price: " << 0.6 * x << endl;
            break;
        default:
            cout << "discount: " << "5 " << "price: " << 0.5 * x << endl;
    }
    
    return 0;
}

这段程序使用了switch语句，根据顾客购物的消费金额进行不同的判断，然后输出相应的折扣和打折后的支付金额。在程序中，将顾客的消费金额除以500得到的商作为判断的依据，然后根据不同的商值进行不同的情况处理，最后输出相应的折扣和支付金额。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
