Create a chess ratings tracker using Maps and pass by reference$/$pointer in C$++$ that has two parts:

Continuously$$prompt the user to input$$player$\text{'}$s names and ratings. The names and ratings should be stored in an appropriate associative container. For example:

Enter name $($q to quit$)$: Zack

Enter rating: $1250$

Enter name $($q to quit$)$: q

After all of the players have been entered, continuously ask the user for a players name and respond with the players rating or "Unknown Player" if the player does not exist.

Find player $($q to quit$)$: Zack

Zack has a rating of $1250$

Find player $($q to quit$)$: Joe

Unknown Player

Find player $($q to quit$)$: q

Bye

Looking for name$/$date$/$e$-$mail and an overview comment at the top along with program comments and testing. $$Your program should use pass by reference$/$pointer for user input. $$ Your program should also guard against chess ratings above $3000$ and below $100.$ Also remember to include testing at the end of your program. $$
