1. Write down a piece of code that defines two (named) constants of type string whose values are your first name and your last name. Select meaningful identifiers for these constants, and use the book's idea on how to distinguish between a variable and a constant.
2. Use the constants that you defined in Problem 1 to assign, to the variable fullName, a string that is your full name. For example, if your first name is Gang, and your last name is Xiang, the value of the variable fullName should be Gang Xiang.
