Can someone tell me if this part of the code looks normal in syntax? Especially everything after this comment //Creating a new array, increasing the size by 1. If not, what to change
void STO::addNewCar() {
    cout << "Enter the brand of the car: ";
    string brand;
    cin >> brand;
    cout << "Enter the color of the car: ";
    string color;
    cin >> color;
    cout << "Enter the registration number of the car: ";
    string registrationNumber;
    cin >> registrationNumber;
    double volume, power;
    cout << "Enter the volume of the car engine: ";
    cin >> volume;
    cout << "Enter the power of the car engine: ";
    cin >> power;
    cout << "Enter the serial number of the car engine: ";
    string serialNumber;
    cin >> serialNumber;
    //Create a new engine
    Engine newEngine(volume, power, serialNumber);
    // Create a new car with an engine
    Car newCar(newEngine, brand, color, registrationNumber);
    // Create a new array, increase the size by 1
    Car* newCars = new Car[numberOfCars + 1];
    // Copy existing objects to a new array
    for (int i = 0; i < numberOfCars; ++i) {
        newCars[i] = cars[i];
    }
    // Add a new car to the array
    newCars[numberOfCars] = newCar;
    // Free memory
    delete[] cars;
    //Updating the pointer to the array
    cars = newCars;
    // Increment the car counter
    numberOfCars++;
}
