Create a program that asks the user for their first name. Once they enter something into the Serial monitor, it then asks them for their last name. After entering another string, the program then combines the two strings with a space in between and prints it back to the Serial Monitor.

For example, here the program asks for my first name. 

Once I enter my first name, the program asks for my last name. 

Upon entering my last name, the program prints a message containing my first and last names. 

You can choose to have the program repeat the process, if you wish.

Hint: use String objects.
