Problem in C++ task

Question

#include <iostream>
using namespace std;
int main() {
int ages[5];
int min = ages[0];
for (int i = 0; i < 5; ++i) {
cin >> ages[i];
}
if(sizeof(ages)==20){
for(int i=0; i<5; ++i){
if(ages[i]<min)
min = ages[i];
int discout = min/100 * 50;
cout<<50-discout;
}
}
else
cout<<sizeof(ages)/4*10;
return 0;
}

Answer 1

Don't need to take min variable & don't need to compare the size of the array just sort the array with this.
for(int i = 0; I < 4; i++) {
for(int j = 0; j < 4; j++) {
if (ages[j] > ages[j+1])
ages[j] = ages[j+1];
}
}
ages[0] will be the smallest age.

Answer 2

1) What are you trying to do when comparing sizeof (ages) with 20 ? ( It will always be true in your case )
2) why is the calculation of the discount in integers ?
3) why are you printing the output on every iteration of the loop ?
