Answer / Explanation:

To properly answer this question, we will utilize the python programming language.

The Python programming language is a general purpose and high level programming language. You can use Python for developing desktop GUI applications, websites and web applications. Also, it allows you to focus on core functionality of the application by taking care of common programming tasks.

Now, moving forward to write the program, we have:

def string_test(s):

   d={"UPPER_CASE":0, "LOWER_CASE":0}

   for c in s:

       if c.isupper():

          d["UPPER_CASE"]+=1

       elif c.islower():

          d["LOWER_CASE"]+=1

       else:

          pass

   print ("Original String : ", s)

   print ("No. of Upper case characters : ", d["UPPER_CASE"])

   print ("No. of Lower case Characters : ", d["LOWER_CASE"])

string_test('Enter Phone Number')
