hello. I believe the preprocessor directive calls the metadata the main function will be based on. The main function marks the body of the code. Expression statements will return a string of text or similar expression or value to the terminal. Declaration statements I believe will instantiate the values of any variables or set the type of said variables. These are letting the user know what the objective is for the game and making sure what they are entering is being accepted. Return statement ensures no errors are returned upon compiling the code.
