如何从 C 函数正确返回二维数组？

#include <iostream>
using namespace std;

// Returns a pointer to a newly created 2D array with dimensions [height x width]
int** MakeGridOfCounts(int height, int width) {
  int** grid = new int*[height];  // Dynamically allocate an array of pointers to rows
  
  for (int i = 0; i < height; i++) {  // Allocate each row and set its columns to 0
    grid[i] = new int[width];
    fill_n(grid[i], width, 0);
  }
  
  return grid;
}

int main() {
  int** grid = MakeGridOfCounts(6, 6);  // Get a 6x6 grid (initialized with 0s)
  
  // Do something with the grid...

  // Release allocated memory
  for (int i = 0; i < 6; i++) {
    delete[] grid[i];
  }
  delete[] grid;
  
  return 0;
}
