There is comparing between two programs, one is 2d array by using only subscriber and anther is 2d array but using the pointer.

From the above comparison between two programs, we see that 2d array using only subscriber is faster than the 2d array by using the pointer.



2d array by using pointer is work with the address of the variable. That means it takes the value of the variable address. For that reason, it is slower than the 2d array by using only subscriber.
