How to initialize a 3D contiguous array in C -

i know how potentioal non-contiguous array in following way:

int main () {   int ***array = (int***)malloc(3*sizeof(int**));   int i, j;    (i = 0; < 3; i++) {     // assign array[i], not *array[i] (that dereference uninitialized pointer)     array[i] = (int**)malloc(3*sizeof(int*));     (j = 0; j < 3; j++) {       array[i][j] = (int*)malloc(3*sizeof(int));     }   }    array[1][2][1] = 10;    return 0; } 

with code above, array[0][j] blocks can not contiguous. contiguous, feel need malloc in way

int* array = (int*)malloc(3*3*3*sizeof(int)); int** y = (int**)malloc(3*3*sizeof(int**)); int*** x = (int***)malloc(3*sizeof(int***));    for(i = 0; < 3; i++)     {       vals = vals + i*m*n;       x[i] = &vals;       for(j = 0; j < 3; j++)     {     x[i][j] = vals + j * n;     }     } 

however, got troulbe address assignment. not c programmer, can correct fault? in advance...

int*** x = (int***)malloc(3*sizeof(int***)); 

should be

int*** x = (int***)malloc(3*sizeof(int**)); 

now initialization can :

  for(i = 0; < 3; i++)   {     x[i] = y + 3*i;     for(j = 0; j < 3; j++)     {       x[i][j] = array + i*3*3 + j*3;     }   } 

so x[0] points first element of y, x[1] fourth, etc. , x[0][0]=y[0] first of array, x[0][1]=y[1] fourth of array, etc.
