The program prompts the user for their choice and the name of the html file. The program then reads the html file and stores the contents in an array. The program then reads the array and stores the contents without the html tags in another array. The program then outputs the contents of the array to the console or to a txt file. The program then displays a message to the user indicating that the output was written to a txt file. The program then terminates. */
