        }

        float direction = target_altitude > altitude ? 1 : -1;
        while (altitude != target_altitude) {
            altitude += direction; // Ascend or descend.
            std::cout << 'Flying. Current altitude: ' << altitude << 'm
';
            std::this_thread::sleep_for(std::chrono::seconds(1)); // Wait for a second.

};

int main() {
    Drone drone;
    drone.takeOff();
    drone.flyToAltitude(50.0f);
    drone.land();
    return 0;
}

Code Output:

The output of the code is a text stream that simulates the drone taking off, flying to a specific altitude, and landing. It will look like this:

Ascending. Current altitude: 5m
Ascending. Current altitude: 10m
...
Drone reached maximum altitude of 100m.
Flying. Current altitude: 95m
Flying. Current altitude: 90m
...
Reached target altitude of 50m.
Descending. Current altitude: 48m
Descending. Current altitude: 46m
...
Drone has landed.

Code Explanation:

The provided C++ code snippet simulates a drone’s flight sequence in a real-time aerial system. The Drone class encapsulates attributes such as altitude and is_flying, which represent the drone’s current altitude and its flying state.

The takeOff function simulates the takeoff procedure, where the drone’s altitude gradually increases at a constant speed defined by TAKEOFF_SPEED until it reaches the predefined MAX_ALTITUDE. The std::this_thread::sleep_for function is used to introduce a delay between altitude changes, simulating real-time behavior.

The land function reverses the process of takeoff. It gradually decreases the altitude of the drone at LANDING_SPEED until the drone safely lands back to the ground (altitude reaches zero).

The function flyToAltitude allows the drone to fly to a specific altitude if the drone is already in the air. It checks whether the target altitude is within the drone’s operational limits before attempting to change altitude. If it isn’t flying or the target altitude is too high, it will print an error message.

This example makes use of modern C++ features such as thread for pausing the program to simulate the real-time flight, and constexpr for defining constants which represent the physical attributes of the drone. It’s a fundamental and rudimentary simulation that demonstrates the concept of controlling a drone via software.
