/* write a program that reads a character, 
if the character is 'a' or 'A' the program prints an ASCII value of 'a' and 'A', 
if the character is 'b' or 'B', the program  prints the character and its ASCII value, 
if the character is 'c' or 'C', the program prints the sum of ASCII values of 'c' and 'C'
if the character is not one of the above, the program prints an error message

USE SWITCH statement - can be used with characters or integers only.
