How to Return a 2D Array Using Arrays

Instead of directly returning the 2D array using its name, as in the given code, you can create and return a pointer to the array. The following code snippet demonstrates how to accomplish this:

int** create2DArray(int rows, int cols) {
  int** array = new int*[rows];  // Allocate row pointers
  for (int i = 0; i < rows; i++) {
    array[i] = new int[cols];  // Allocate columns for each row
  }
  return array;
}

By using a pointer to the array, you can return the 2D array without violating the language rules and ensure that the array is properly deallocated when it is no longer needed.
