Question

As memory is considered to be single dimensional, then can anyone kindly tell (and explain) that “How multi-dimesional arrays are represented in Memory”.

Thanks in advance.

Answer 1

It depends on the language implementation but more often than not they are represented as a consecutive memory block row after row.
I wrote about it on my blog:

Allocated arrays are stored in the heap memory as a continues chunk of
memory. Two dimensional arrays (same as in the example above) are
stored similarly – each line of the array (index x,0 – x,n) stored
together and so to reach the x,y cell we have to go to the j + (i *
width) place.

For more details on hoiw arrays are implemented in C++ take a look at:
C++ Notes: 2-D Array Memory Layout

Most of the programming languages I encoutered use a similar method to storing multidimensional arrays.
