Access array elements using index Dry Run in C

Access array elements using index is an interactive C dry run visualizer from the Arrays 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.

Access array elements using index Program Code

#include <stdio.h>
int main() {

    printf("Middle element: arr[2] = %d\n", arr[2]);
    printf("Last element: arr[4] = %d\n", arr[4]);
    
    // Modify element at index 3
    arr[3] = 100;
