Scalar Multiplication of 3D Array Dry Run in C

Scalar Multiplication of 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.

Scalar Multiplication of 3D Array Program Code

#include <stdio.h>
int main() {
    int arr[2][2][3] = {1,2,3,4,5,6,7,8,9,10,11,12}, i, j, k;
    int scalar = 3;
    int layers=2, rows=2, cols=3;
    
    printf("Original array:\n");
    for(i =0;i<layers;i++) {
        printf("Layer %d:\n",i);
        for(j =0;j<rows;j++) {

                printf("%3d ", arr[i][j][k]);
