To Compile

• I used gcc version 12.1.0 supporting c++20 .....

1. open terminal and navigate to the project directory.
2. compile using the command: g++ -std=c++20 -o main main.cpp.
3. Run the executable

[1] Problems Identified

• iostream header not included
• std::optional not included
• remove() and remove_if() not members of therefore included std::algorithm - ref https://en.cppreference.com/w/cpp/algorithm/ranges/remove

[2] Implementing Phantom Power Feature

• added a boolean member to device class - "phantomPowerStatus"
• added setter and getter (as string to be displayed - for the sake of clarity for the user)
• inside runApp() method added set-phantom-power to list of commands displayed to user
• also added line to show phantom-power when user runs the command 'status'
• processed command input by user inside processDeviceCommand() method

[3] Ensuring Preamp level in range

• just a simple if, else statement to check - inside setPreampLevel method

• also added try catch block inside processCommand to ensure non-numerical values for preamp values are handled
