EXCERCISE:
// 1. create an enum for the color of shirts called shirtColor and set it to the options of either RED or WHITE or BLUE
// 2  create a data of shirtColor called defaultChoice which is a constant set to the color BLUE 
// 3. create a data of shirtColor called choice and don't initiate the value
// 4. create a function called setWhite which changes the shirt color of shirtColor to white
// 5. create a function getChoice which returns the current choice of shirtColor
// 6. create a function getDefaultChoice which returns the default choice of shirtColor
