a. Write a function named countDigits that accepts a positive integer as its parameter and returns the number of digits in that number.

For example, the number 8546587 has seven digits, so the call countDigits(8546587) should return 7.

You may assume that the value passed to your method is non-negative.

b. Write a program to input an integer n and call the above function in part a if n is positive, else give Value must be Positive message. Inputting will stop when 0 is entered.
