c - "Use of uninitialised value" despite of memset -

I assign a 2d array and use the memeset to fill it with zero.

  # include & lt; Stdio.h & gt; #to & lt include, string.h & gt; #to & lt include, stdlib.h & gt; Zero main () {int m = 10; Int n = 10; Int ** array_2d; Array_2d = (int **) malloc (m * size (int *)); If (array_2d == NULL) {printf ("\ n malloc could not be arrayed 2d \ n"); Exit (1); } For (int i = 0; i & lt; m; i ++) {((array_2d) [i]) = malloc (n * sizeof (int)); Memset (((array_2d) [i]), 0, sizeof (n * sizeof (int)); } For (int i = 0; i & lt; 10; i ++) {for (int j = 0; j & lt; 10; j ++) {printf ("(% i,% i) =" , I, j); Fflush (stdout); Printf ("% i", array 2D [i] [ja]); } Printf ("\ n"); }}  

Then I use Valgrind [1] to check memory errors I get the following error: conditional jump or move on unmanaged value (values) Depends line 24 ( printf ("% i", array_2d [i] [j]); ). I always thought that there is a function to start the MEMAX arrames, how can I get rid of this error?

Thank you!

On this line:

  / * sizeof ( N * Sizeof (int)) is a value of type size_t tains means that you are able to start only the size of the array (Akar_ti) * / Memetset (((Aaradeedeedeedi) [i]), 0, Akarf (N * Akarf (Int)));  

It should be:

  memset ((array_2d) [i]), 0, n * sizeof (int));
