Multi-dimensional arrays are generally Employed in numerical algorithms (generally from used linear algebra) to retail store matrices. The framework from the C array is well matched to this particular endeavor. On the other hand, given that arrays are handed simply as pointers, the bounds from the array needs to be identified preset values or else explicitly passed to any subroutine that requires them, and dynamically sized arrays of arrays can not be accessed utilizing double indexing.
