I need to create a simple substituiton cypher program.    Ask the user for the message to encrypt. Display back to the user the Cipher Text (the encrypted result). Let the user enter multiple phrases displaying the cipher text after each one. Use the sentinel value of QUIT to end the program. Use a function to display a message at the end that says in your owns "Have a nice day" and display the number of messages that were encrypted. Use at least one other function in the program, that function has to either accept an parameter, return a value or do both. Convert all text in the original message to lower case and then display the cipher text in lower case also. (this will make it easier to convert)
