Declare, Initialize, and Print 3D Array Dry Run in C

Declare, Initialize, and Print 3D Array is an interactive C dry run visualizer from the Multi D 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.

Declare, Initialize, and Print 3D Array Program Code

#include <stdio.h>

    int arr[2][3][4] = {
