Box-and-Pointer Diagrams

This video lecture explains box-and-pointer diagrams, which are a visual model for objects, variables and references. Box-and-pointer diagrams are also important for understanding and explaining data structures. We’ll develop the ideas behind box-and-pointer diagrams by thinking about how programs use memory.

For the best experience, watch in full-screen HD.

The video includes demonstrations using IDLE (Python 3), the interactive memory model and the live Python visualiser.
