Difference between “pointer to int” and “pointer to array of ints”

Question

int main()
{
    int (*x)[5];                 //pointer to an array of integers
    int y[6] = {1,2,3,4,5,6};    //array of integers
    int *z;

Hope this code helps.

#include 
#include 
#define MAXCOL 4
#define MAXROW 3

int main()
{      
      int i,j,k=1;
      int (*q)[MAXCOL];      //pointer to an array of integers

      /* As malloc is type casted to "int(*)[MAXCOL]" and every 
         element (as in *q) is 16 bytes long (I assume 4 bytes int), 
         in all 3*16=48 bytes will be allocated */

      q=(int(*)[MAXCOL])malloc(MAXROW*sizeof(*q));
