Following the class diagram shown below, create the class RecordPlayer. An RecordPlayer represents a stereocomponent that can play vinyl records.. Please review the class and the sample driver code. There is a specific order to the way the class methods should be called. In other words, you can't plop the Needle unless there actually is a record on the player and the recordplayer is turned on. You also can't return the Needle unless there is actually a record on the player and the recordplayer is turned on. Your class should enforce these rules and write errors to cout as they occur. A sample driver for this class is shown below.

Rules of the record player

You can affix a platter if the record player is on or off and the needle is not ploped

Record player must be on and must have record affixed to the platter to plop the needle on the record

Can only return the needle if the record player is on and there is a record on the player

Performing the same action twice results in a "no-op" where nothing changes. For example, you can't plop an already plopped needle, and you can't return a needle that's already returned. Another example: you can't turn on/off a record player that is already on

Record Player Sample Driver Code

//declare 6 RecordPlayers

RecordPlayer good_r, bad_r1, bad_r2, bad_r3, bad_r4, bad_r5;

//first test correct

good_r.turnOn();

good_r.affixPlatter("Barrow Manila I");

good_r.plopNeedle();

good_r.returnNeedle();

good_r.turnOff();

//bad test, plops needle without turning it on or putting record on

bad_r1.plopNeedle();

//turns it on but no record on platter

bad_r2.turnOn();

bad_r2.plopNeedle();

//not on nor has album on platter

bad_r3.returnNeedle();

//turned on but no album

bad_r4.turnOn();

bad_r4.returnNeedle();

//not turned on

bad_r5.affixPlatter("Barrow Manila I");

bad_r5.plopNeedle();
