LEARN Theory for this problem

+

An `if` / `else if` / `else` chain checks alternatives from top to bottom. Put more specific or higher-priority conditions first.

Connection to “Age Category”: here, branching selects a case using a Boolean condition; test order matters when cases overlap.

#include <iostream>
#include <algorithm>
using namespace std;
int main() {
    long long n;
    cin >> n;
    if (n < 13) cout << "child";
    else if (n < 18) cout << "teen";
    else if (n < 65) cout << "adult";
    else cout << "senior";
    cout << '\n';
    return 0;
