1. Prompt and accept from user 3 strings that represent the first, last and middle names individually.
2. Create a new string to represent the corresponding full name, and display it on screen in format: Lastname, Firstname, Middle name.
3. Prompt for and accept from the user another string that consists of 8 or more characters without any blanks (spaces and tab). If the user enters a string that is shorter than 8, continue to prompt for the user and accept a new string until a valid string is entered.
4.For this string, finish the following two things in order: (you probably need to declare a new string)
a. Change the first three characters to "Abc". Change the last three characters to their successors ('z'->'a','Z'->'A') For example, "Def: becomes "Efg", and "uSz" becomes "vTa". You may need the ASCII table for help.
b. Display the original string (entered by the user) backwards. For exmple, "programming" will be displayed as "gnimmargorp".
