Resizing arrays. Dynamically allocating an array allows you to set the array length at the time of allocation. However, C++ does not provide a built-in way to resize an array that has already been allocated. 2019-05-09 · We can create an array of pointers also dynamically using a double pointer. Once we have an array pointers allocated dynamically, we can dynamically allocate memory and for every row like method 2. #include dynamically allocated arrays Dynamically allocated arrays are allocated on the heap at run time.
