/*
Write a program to ask the user to enter an entire input line 
from the keyboard. Then read this string (call it line) using 
getline. Then encrypt the string as follows: replace every 
character in line by the reverse of its ASCII position. 
Store the new string in a variable called encrypted. 
Then print encrypted.
