How can I make a function which returns an array? I tried this

const int WIDTH=11;
const int HEIGHT=11;

int main() {
  char A[WIDTH][HEIGHT];
  A=rand_grid(WIDTH,HEIGHT);
  return 0;
}

// Initializes a random board.
char[][] rand_grid(int i, int k) {
  char* A[i][k];
  for(j=0;j<i;++j) {
    for(l=0;l<k;++l) {
      A[j][l]=ran(10);
    }
  }
  return A;
}

// Returns a random number from the set {0,...,9}.
int ran(int i) {
  srand((unsigned int) time(0));
  return(rand()%10);
}
