Weblist listOfItems; SubclassOfItem item; item.id = itemCrowbar; item.extra = "hello"; listOfItems.push_back(item); Or you can create a list of 'smart pointers' (std::unique_ptr) to items: which behave like pointers to Items except that you don't need to delete the Item (the Item is deleted when the smart pointer which contains it is destroyed). WebTherefore it is must to check if a given index position exists in the array or not before accessing element at that index position. To check if index position is valid or not, first we need to fetch the size of the array, and then we can check, if the given index position is either greater than or equal to zero and less than the size of the array.
