Make an InstanceCounter class

a$.$ Make a global variable to count the number of times an object was instantiated. Make another global variable to count the number of an object was deleted.

b$.$ Make a new class named InstanceCounter. In its constructor, increment the number of times an object was instantiated. In its destructor, increment the number of times an object was deleted.

c$.$ Add a function that prints these values:

$($The autograder will look for the substrings "instantiated: and "deleted: $",$ so don't change those.$)$

d$.$ Add a menu option to your program to report the number of instantiations and deletions:

cout $"11.$ Memory report" $$ endij When this option is selected, call that function to report the number of instantiations and deletions

e$.$ Make your LinkedList class inherit from InstanceCounter.

f$.$ Make your LinkedListNode classes inherit from InstanceCounter.

Make your CharMap class inherit from InstanceCounter.

h$.$ Make your Dataset class inherit from InstanceCounter:
