Find Average of Each 2D Slice (Layer-wise Average) 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.

Find Average of Each 2D Slice (Layer-wise Average) Program Code

#include <stdio.h>

    int layers = 3, rows = 4, cols = 5;
    
    // Initialize with pattern: layer × 100 + row × 10 + col
    for(i = 0; i < layers; i++)

            for(k = 0; k < cols; k++)
