C - Segmentation fault with pointer to array -

i'm hoping can me little piece of code. it's stupid test, dont know doing wrong. it's this:

#include <stdio.h>  int **ipp;  int ventas [3][4] = {{1, 2, 3, 4}, {5, 6, 7, 8}, {9, 10, 11, 12}};  int main(void){      ipp = (int **)ventas;      printf("%d\n", **ipp);      return 0; } 

it compiles (i'm using gcc), when execute keep getting segmentation fault. doing wrong? think has un-initalized pointer, 'ventas' array initialized, , it's assigned **ipp.

• a pointer-to-pointer not array. nor pointer 2d array. aren't slightest compatible. forget pointer-to-pointers in case.

• if want pointer 2d array, must write int (*ipp)[3][4] = &ventas;

• you can't print pointer using %d format specifier. should use %p.

corrected code printing address of 2d array:

#include <stdio.h>  int main(void){   int ventas [3][4] = {{1, 2, 3, 4}, {5, 6, 7, 8}, {9, 10, 11, 12}};   int (*ipp)[3][4];    ipp = &ventas;   printf("%p\n", ipp);    return 0; }
