What is wrong with my code ? The min gets me the maxiimum number in the array??

Question

#include <iostream>
using namespace std;

int main() {
int ages[5];
int min;
int sum;
int ans;

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

for (int j = 0; j < 5; j++) {

sum = sum + ages[j];
}

for (int k = 0; k < 4; k++) {

if(ages[k] < ages[k++]){
min = ages[k];
}
else{
min = ages[k++];
}

}

ans = (sum*(min/100));

cout << min << endl;
cout << sum << endl;
cout << ans << endl;

return 0;
}
