c - Segmentation fault, 2-Dimensional Matrix, malloc -

i'm trying create 2-dimensional array using malloc. code seems correct when try set values, receive "segmentation fault" message.

#include <stdio.h> #include <stdlib.h>  int main(){     int i, j;     int **m = (int **) malloc(5 * sizeof(int));      if(m == null){         printf("error");         getchar();         exit(-1);     }      for(i = 0; < 5; i++){         m[i] = (int *) malloc(5 * sizeof(int));          if(m[i] == null){             printf("error");             getchar();             exit(-1);         }     }      for(i = 0; < 5; i++){         for(j = 0; j < 5; j++){             printf("%d %d\n", i, j);             m[i][j] = 0;         }     }      for(i = 0; < 5; i++){         for(j = 0; j < 5; j++){             printf("%d ", m[i][j]);         }         printf("\n");     }  } 

thanks.

change

int **m = (int **) malloc(5 * sizeof(int)); 

to

//---------------------------------------v int **m = (int **) malloc(5 * sizeof(int *)); 

your code fail size of int not equal size of pointer variable.
