Define a class counterType to implement a counter. Your class must have a private data member counter of type int. Define a constructor that accepts a parameter of type int and initializes the counter data member. Add functions to: Set counter to the integer value specified by the user. Initialize counter to 0. Return the value of counter with a function named getCounter. Increment and decrement counter by one. Print the value of counter using the print function. Example output: Counter = 0. The value of counter must be nonnegative.

Recurrence relation

A recurrence relation or recursive relation is an equation that represents a function in terms of the values of its smaller inputs. Every recurrence relation T(n) is a recursive function of integer n and consists of a base case and a recursive case.
