1. Create a class: “Prime” with private data members: upper_limit (int), lower_limit (int) and parameterized constructor, which initializes the values of both data members. Apart from initialization, this constructor also displays the count of prime numbers from upper_limit to lower_limit. [Example: upper_limit:15, lower_limit:10, count of prime numbers is:2 (11 and 13), also make sure the value of upper_limit should be greater than lower_limit].
