The Data Structure
Captions available
The idea
A data structure is a complex data type with two equally important parts: a specific way of organizing a collection of elements, and specific operations such as adding, retrieving, and removing them.
In practice
A gradebook organizes scores by student and by assignment, and grants lookup, entry, and correction.
Where people slip
Organization without operations is half a structure.
