Решение с тернарен оператор:

#include <iostream>

using namespace std;

int main() {
    double degrees;
    cin >> degrees;

    string weather =
        degrees >= 5 && degrees < 12 ? "Cold" :
        degrees >= 12 && degrees < 15 ? "Cool" :
        degrees >= 15 && degrees <= 20 ? "Mild" :
        degrees > 20 && degrees < 26 ? "Warm" :
        degrees >= 26 && degrees <= 35 ? "Hot" : "unknown";

    cout << weather << endl;

    return 0;
