Store details of multiple students Dry Run in C

Store details of multiple students is an interactive C dry run visualizer from the Structures Arrays programs section. Study the source code, then use the execution controls to follow each step, variable update, highlighted line, and console output.

This page provides a browser-based dry run with source-code highlighting, auto-scroll, voice narration controls, and execution output for learning the program step by step.
