Array values are stored at consecutive memory addresses, i.e., one by one. So to display an array using pointer use can add the index to the current pointer address. Like to display a[2], you can use *(p + 2). So your correct code will be this: int a[20]; int[] *p; p=&a; for(int i=0;i<5;i++) cout<< *(p + i);
