What time is it?

Question

#include <iostream>
using namespace std;

// We have n (n <= 10 000 000) seconds from the beginning of the day. What time will clock show? Format -> h:mm:ss

int main() {
int n, hours, minutes_t, minutes_u, seconds_t, seconds_u;

cin >> n;

hours = n / 3600 % 24; // f.e. 125489 / 3600 % 24 = 10 hours

minutes_t = n / 60 % 60 / 10; // f.e. 125489 / 60 % 60 / 10 = 5 minutes (tens)
minutes_u = n / 60 % 10; // f.e. 125489 / 60 % 10 = 1 minutes (units)
