The Memory Probe: Pointer Arithmetic Visualizer

Deep dive into C's memory model, pointer arithmetic, and the handling of arrays and strings. The Memory Probe: Pointer Arithmetic Visualizer turns that idea into something you can manipulate directly and watch respond.

Deep dive into C's memory model, pointer arithmetic, and the handling of arrays and strings. It focuses on Pointer Arithmetic and Offsets, Null-terminated Strings, Pass-by-reference, Dereferencing and Address-of Operators, Void Pointers from the “Memory Management, Objects, and Pointers” section.

You can drag elements directly on the canvas; a dropdown switches between scenarios; the “ptr--”, “ptr++”, “0”, “[2]” buttons run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.

This course provides a comprehensive exploration of the interface between software and hardware, focusing on the C programming language and the Unix/POSIX operating system model. Students learn to manage low-level memor… This demo is the interactive piece for the “Memory Management, Objects, and Pointers” section.

You'll build intuition for Pointer Arithmetic and Offsets, Null-terminated Strings, Pass-by-reference, Dereferencing and Address-of Operators, Void Pointers — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on Systems Programming in C and Unix Environments alone.
