Transpose 4D Array (Swap Two Dimensions) Dry Run in C

Transpose 4D Array (Swap Two Dimensions) 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.

Transpose 4D Array (Swap Two Dimensions) Program Code

#include <stdio.h>
int main() {
    int arr[2][3][4][2], i, j, k, l;
    int transposed[4][3][2][2];
    int a=2,b=3,c=4,d=2;
    
    for(i =0;i<a;i++) for(j =0;j<b;j++)
        for(k =0;k<c;k++) for(l =0;l<d;l++)
            arr[i][j][k][l] = i*1000 + j*100 + k*10 + l;
    
    // Swap dim0 and dim2
    for(i =0;i<a;i++) for(j =0;j<b;j++)
        for(k =0;k<c;k++) for(l =0;l<d;l++)
            transposed[k][j][i][l] = arr[i][j][k][l];
    
    printf("Original: %d×%d×%d×%d\n", a,b,c,d);
    printf("Transposed: %d×%d×%d×%d\n", c,b,a,d);
    return 0;
