Hello World
Create a program to ask for a user's name, then output a greeting to them
Examples:
If they input their name as Fred, then the program should output Hello Fred!
Extension:
Add code to keep asking the user to try again, if they don't enter a valid name (e.g. no characters). You could add additional validation rules yourself if you'd like - for example, perhaps the name has to only contain characters in the set A-Z
