Help me in solving DSAAGP07 problem

My issue

Enter the position to insert (0 to 5): Enter the new element to insert: Updated array: 10 20 0 30 40 50

My code

#include <stdio.h>

int main() {
    // Step 1: Initialize the array with extra space for insertion
    int arr[10] = {10, 20, 30, 40, 50}; // Initial array
    int n = 5; // Current size of the array
    int pos, newElement;

    // Step 2: Input the position and new element
    printf("Enter the position to insert (0 to %d): ", n);
    scanf("%d", &pos);
    printf("Enter the new element to insert: ");
    scanf("%d", &newElement);

    // Step 3: Validate the position
    if (pos < 0 || pos > n) {
        printf("Error: Invalid position.\n");
        return 1;
    }

    // Step 4: Shift elements to the right from the last element to the position
    for (int i = n; i > pos; i--) {
        arr[i] = arr[i - 1];
    }

    // Step 5: Insert the new element at the specified position
    arr[pos] = newElement;

    // Step 6: Update the size of the array
    n++;

    // Step 7: Print the updated array
    printf("Updated array: ");
    for (int i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }
    printf("\n");

    return 0;
}
