# C++

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

Mando Be specific, What do you need help for?

You don't even need an array, just a for and two ifs. One for the first minimum and other to find the discount

+1

You don't need to sort the array – just iterate once and keep the minimum in a temporary variable.

#include <iostream> using namespace std; int main() { int ages; for (int i = 0; i < 5; ++i) { cin >> ages[i]; } return 0; } What i got rn

Its wants go take the youngest age of the person in the group and make their age a discount

Mando You can perform sorting algorithm to determine the youngest one.

Havent leanred bubble sort yet

Mando This is the only efficient way i could tell right now. However if you wanna do it with the if/else condition then there's a way but it would be messy to look.

Iteration means "use a loop"

Lisa still a bit confufussed on how to use a loop and use a temp varible to get the lowest number

0

* int temp = 0; * loop over array: on each iteration check if the current array element is smaller than temp. If so, assign the current element value to temp * after the loop, temp is the minimum value of the array

Mando compare each index with their next one & pick the smaller among them until you find the smallest one.

#include <iostream> #include <iomanip> using namespace std; int main() { int ages; for (int i = 0; i < 5; ++i) { std::cin >> ages[i]; } //your code goes here const double ticket_cost = 10; int youngest = ages; for (int i = 0; i < 5; i++) { // 0 > 55 if (youngest > ages[i]) { youngest = ages[i]; } } int peoples = (sizeof(ages) / sizeof(int)); double price = peoples * ticket_cost; double discount = (price - ((price*youngest / 100))); std::cout << std::setprecision(3) << discount << std::endl; return 0; }
