Ticket office project

Question

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

There's a code below buh I just need an explanation for it thanks

Answer 1

#include <iostream>
using namespace std;

int main() {
int ages[5];

for (int i = 0; i < 5; ++i) {
cin >> ages[i];
}
//your code goes here
float youngest_person, cost ;
youngest_person = ages[0];
for (int x = 1; x < 5; ++x)
{
if ( youngest_person > ages[x])
youngest_person = ages[x];
}
cost = 50 - (50*youngest_person/100);
cout << cost << '\n';

return 0;
}
