Replace element with new value (position-based with validation) Program Code

#include <stdio.h>
int main() {
    int arr[] = {10, 20, 30, 40, 50}, i;
    int n = 5, pos, newValue;
    
    printf("Enter position (0-%d): ", n-1);
    scanf("%d", &pos);
    
    if(pos >= 0 && pos < n) {
        printf("Enter new value: ");
        scanf("%d", &newValue);
        arr[pos] = newValue;
        
        printf("Array after update: ");
        for(i = 0; i < n; i++) {
            printf("%d ", arr[i]);
        }
    } else {
        printf("Invalid position!");
    }
