Search record using function Dry Run in C

Search record using function is an interactive C dry run visualizer from the Struct Functions Pointers 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.
