Dynamic array - C++ I need help implementing these functions please. The Main has already been filled out and I am just struggling to complete these functions. The comments in each function specify exactly how the function should work. Try using the iostream library to complete the functions. Thank you. Code:

#include using namespace std; 1 2 3 4 5 6 7 8 const int DEFAULT_CAPACITY = 10; //Default capacity of the dynamic array 10 11 class DynamicArray ( private: int capacity; int _size; int* elements; // Defines the maximum number of elements that this DynamicArray can hold //Keeps track of the current number of elements inserted into this DynamicArray //Pointer to the array where the elements are inserted. public: * Default constructor */ DynamicArray(); //Initialize 'capacity' to DEFAULT_CAPACITY //Allocate memeory for DEFAULT_CAPACITY number of integers and point the allocated memory by 'elements 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 * Regular constructor DynamicArray (const int capacity); * Copy constructor DynamicArray (const DynamicArray); * Move constructor.
