Write ItemList.h and ItemList.c ItemList is used to store a list of Items by their item number. In ItemList.h, use typedef to define the ItemList type which contains the following information: ItemList: int items[MAX_ITEM_LIST]; // the itemNumbers in the list int count; // the number of items in the list Make sure that MAX_ITEM_LIST is defined with a suitable size in your ItemList.h. Add the following interface definitions to ItemList.h: void ItemListInit(ItemList *pItemList); Initializes the ItemList structure pointed to by pItemList as an empty list. int ItemListAddItem(ItemList *pItemList, int itemNumber); Adds item identified by itemNumber to the end of the list. Have the function return the current count of items in the list. int ItemListRemoveItem(ItemList *pItemList, int itemNumber); Removes item identified by itemNumber from the list. Have the function return the current number of items in the list. bool ItemListHasItem(ItemList *pItemList, int itemNumber); Determines if the list pointed to by pItemList contains the item identified by itemNumber. Implement the above functions in the ItemList.c file. Use the provided main program to test your implementation.
