   This program prompts the user for a string
   and displays it back.
   
   1. it will read a string from the user (as shown above),
   2. the string will contain email addresses separated by spaces (one or more spaces between each address)
   3. it will print the name of each person, without the text following the @-sign, and
   4. it will skip the first character of each name. For example if the email is dthiebaut@smith.edu, it will print only thiebaut.
