CD player simulator using c++

Problem

Design a simple CD player simulator. The CD player has the following buttons: "POWER", "EJECT", "PLAY" and "STOP", and a tray where a CD is loaded. User can load a CD only if the tray is open. The tray can be opened only if the power is turned on (regard it as something like a motor-driven tray installed on a PC). If the power is turned off with the tray open, the tray will keep open and the power is turned off.
Implement the following actions of the CD player as methods of class CDPlayer.

• pushPower() -- simulates pushing POWER(on/off) button.
• if the power is turned off, turn on the power, and display "Power turned on."
• if the power is turned on,
• if playing, stop it.

turn off the power, and display "Power turned off."

• pushEject() -- simulates pushing EJECT(tray open/close) button
• if the power is not turned on, display "Power not turned on."
• if the power is turned on,
• if the tray is not open, open the tray and display "Tray opened."
• if the tray is open, close the tray and display "Tray closed."
• pushPlay() -- simulates pushing PLAY button
• if the power is turned on,
• if the media is loaded and tray is closed, begin to play and display "Now playing..."
• otherwise, display "No CD loaded or tray is open."
• pushStop() -- simulates pushing STOP button
• if the power is turned on,
• if it's playing, stop playing and display "Playing stopped."
• loadUnloadMedia() -- simulates loading/unloading media to/from the tray (tray must be open when loading/unloading)
• if the tray is open,
• if the media is loaded, unload the media and display "Media unloaded."
• if the media is not loaded, load the media and display "Media loaded."
• if the tray is not open,
• display "Tray is not open."
