          // 1.  I think the If statements require the computer to determine whether or not the statement below is true or not.  If it is, it prints out something.  If it is not, then it prints out something else.
          // 2.  I think the purpose of the curly bracket is to check to see if the value is matching and if it is then to print out a message.
