这是一个C++程序，用于处理一个售票系统中的折扣计算。当一组5人购票时，根据组内最年轻成员的年龄给予折扣。例如，输入年龄分别为55、28、15、38和63时，因为最年轻的成员15岁，所以享受15%的折扣，总票价为42.5美元。程序首先读取5个人的年龄，然后找出最小年龄并计算相应的折扣价。

You are working on a ticketing system. A ticket costs $10.
The office is running a discount campaign: each group of 5 people is getting a discount, which is determined by the age of the youngest person in the group.
You need to create a program that takes the ages of all 5 people as input and outputs the total price of the tickets.

Sample Input:
55
28
15
38
63

Sample Output:
42.5

The youngest age is 15, so the group gets a 15% discount from the total price, which is $50 - 15% = $42.5

#include <iostream>
using namespace std;

int main() {
    int ages[5];

    for (int i = 0; i < 5; ++i) {
        cin >> ages[i];
    }
     /*for(int i=0;i<5;i++){
     	cout<<ages[i]<<endl;
     }*/
     //检查输入哪些年龄
    double youngest =ages[0];
    for(int i = 0;i < 5;i++){
    	if (ages[i]<youngest)
    	youngest = ages[i];
    	}
    
    //cout<<youngest<<endl;
    //检查最小的对不对
    
    double discount;
    discount=youngest/100;
    double money;
    money=50-50*discount;
  //  求折扣和折扣后的价格
    cout << money;
    return 0;
}
