Compare two structures (manual comparison) Dry Run in C

Compare two structures (manual comparison) is an interactive C dry run visualizer from the Structures 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.

Compare two structures (manual comparison) Program Code

#include <stdio.h>

    int length;

       r1.breadth == r2.breadth && 
       strcmp(r1.color, r2.color) == 0) {
        return 1;  // Equal
    }
    return 0;  // Not equal
}

        printf("Rectangle 1 and 2 are EQUAL\n");
    } else {

    } else {
