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 second largest element in array Program Code

#include <stdio.h>
#include <limits.h>
int main() {
    int arr[] = {12, 45, 23, 67, 34, 89, 21}, i;
    int n = sizeof(arr)/sizeof(arr[0]);
    int first = INT_MIN, second = INT_MIN;
    
    for(i = 0; i < n; i++) {
        if(arr[i] > first) {
            second = first;
            first = arr[i];
        }
        else if(arr[i] > second && arr[i] != first) {
            second = arr[i];
        }
    }
    
    printf("Second largest = %d\n", second);
    return 0;
