passing pointer representing 2d array function in c++

i trying pass 2-dimensional array function through pointer , want modify values.

#include <stdio.h>  void func(int **ptr);  int main() {     int array[2][2] = {         {2, 5}, {3, 6}     };      func(array);      printf("%d", array[0][0]);     getch(); }  void func(int **ptr) {     int i, j;     (i = 0; < 2; i++) {         (j = 0; j < 2; j++) {             ptr[i][j] = 8;         }     } } 

but program crashes this. did wrong?

it crashes because array isn't pointer pointer, try reading array values if they're pointers, array contains data without pointer.
array adjacent in memory, accept single pointer , cast when calling function:

func((int*)array); 

...

void func(int *ptr) {     int i, j;     (i = 0; < 2; i++) {         (j = 0; j < 2; j++) {             ptr[i+j*2]=8;         }     } }
