For this assignment, we will develop a Grocery List class to dynamically manage grocery list items. The Grocery List class should track the number of items in each list and be capable of allocating more memory if the list exceeds its initial capacity.

The input will be a file where each line represents a grocery list. Each line starts with a number indicating the initial capacity of the list, followed by the actual grocery items. The Grocery List class will use a dynamic array of strings to keep track of these items. Note that the initial capacity specified in the input file might be less than the actual number of items, requiring the array to be resized dynamically as needed.
