Need help with ticket office module

Question

The first three test cases work but the fourth and fifth don’t. I tested the code outside of the module and it has worked with all of my random inputs but I think I’m missing something. An explanation as to what I’ve done wrong would be appreciated.

Answer 1

#include <iostream>
using namespace std;

int main() {
int ages[5];

for (int i = 0; i < 5; ++i) {
cin >> ages[i];
}
int lowAge = ages[0];

for (int x = 1; x < 5; ++x){
if (lowAge > ages[x]){
lowAge = ages[x];
}
}
double dis = (lowAge / 100.00) * 50.00;
cout << 50 - dis << endl;

return 0;
}

Answer 2

the variable f is removed as it was useless.

I think the error was because your lowAge was set to 500.(not sure but we don't know the other test cases so its better to not set any raw value here)

And since we have set lowAge to ages[0], we don't need to compare it again so we start the for loop with x=1

Notice in dis how 100 and 50 are changed to 100.00 and 50.00, why? Because that's helpful as it will make the result a double type.

Try this:

include <iostream>
using namespace std;

int main() {
int ages[5];

for (int i = 0; i < 5; ++i) {
cin >> ages[i];
}

double youngest = ages[0];
for (int a = 0; a <5; ++a)
{
if(youngest>ages[a])
{
youngest = ages[a];
}
}

double prezzo = 50 - (50*youngest/100);
cout << prezzo;

return 0;
}

Rkk, your explanation helped clear up some points i wasnt understanding. I wasnt sure how to find the lowest number in an array. Thanks.
