using namespace std;

int main() {
    int month;
    int days;

    cout << "Enter the month number (1-12): ";

    switch (month) {
        case 1: case 3: case 5: case 7: case 8: case 10: case 12:
            days = 31;
            cout << "Number of days in month " << month << " is " << days << endl;
            break;
        case 4: case 6: case 9: case 11:
            days = 30;
            cout << "Number of days in month " << month << " is " << days << endl;
            break;
        case 2:
            days = 28; // Assuming non-leap year
            cout << "Number of days in month " << month << " is " << days << endl;
            break;
        default:
            cout << "Invalid month number. Please enter a number between 1 and 12." << endl;
            break;
    }

    return 0;
}
