C++/Array vs Structures Memory efficieniency


I have a qustion.  Why is it better to use structures than arrays.  Is it because it uses less memory?  If it does how does it do it and why?

Kenny , Thank you for your question.

Except in certain cases where structures are padded, there is no difference in the amount of memory used by a structure or an array. They are different ways to access memory locations; arrays use element indices and structs use member variable names.
