Write a program (just a main) that creates a vector of type string to represent a grocery list. let the user put as many items in the grocery list as they would like. then create a menu with the options 1) display grocery list, 2) add item3) remove item and 4)quit. #2 should let the user add another item to the list and #3 should let them remove an item. #1 should display the current list. the list should loop until the user picks 4 to quit. since vectors are so powerful this shouldn't be too hard.
