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. WebIn C++ smart pointers come in multiple flavors, most importantly the unique_ptr. The unique_ptr is basically a single ownership and scoping construct.
