Write an application that allows a user to enter the names and birth dates of up to 10 friends. continue to prompt the user for names and birth-dates until the user enters the sentinel value “zzz” for a name or has entered 10 names, whichever comes first. when the user is finished entering names, produce a count of how many names were entered, and then display the names. in a loop, continuously ask the user to type one of the names and display the corresponding birth-date or an error message if the name has not been previously entered. the loop continues until the user enters “zzz” for a name.
