Module 7: Lab 7


12a Write a program that includes a function to read (at least 100) strings into an array. 
Allow the user to either add a string or print out the contents of the array. 
Be sure to stop “printing” at the end of the entered values -- don’t “print” after the end of the user’s entered data. 
Be sure to give the user the chance to leave the program.

An option in a function that can remove a string from the array (and compress the array) based on its location in the array. 
Make sure that the “print” option reflects the removed string.
