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.

Modify all occurrences of a value Program Code

#include <stdio.h>
int main() {
    int arr[] = {10, 20, 30, 20, 40, 20}, i;
    int n = 6, oldVal = 20, newVal = 25;
    
    for(i = 0; i < n; i++) {
        if(arr[i] == oldVal) {
            arr[i] = newVal;
        }
    }
    
    printf("Array after update: ");
    for(i = 0; i < n; i++) {
        printf("%d ", arr[i]);
