/* Spring 2023 - PA2.c

	continuation of Lab 8

	Splits up the functions into separate files.
	Adds a word search function to the program.
	The menu will now be the following:
		1. print the poem 
		2. show number of lines in the poem
		3. convert the case
		4. search for a word 
		5. quit the program
