Write code to insert data in an array at a particular position

 
#include <stdio.h>

int main()
{
    int arr[100], n, pos, value, i;

    // Read size of array
    printf("Enter number of elements: ");
    scanf("%d", &n);

    // Read array elements
    printf("Enter array elements:\n");
    for (i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }

    // Read position and value
    printf("Enter position to insert (1 to %d): ", n + 1);
    scanf("%d", &pos);

    printf("Enter value to insert: ");
    scanf("%d", &value);

    // Validate position
    if (pos < 1 || pos > n + 1) {
        printf("Invalid position!");
        return 0;
    }

    // Shift elements to the right
    for (i = n; i >= pos; i--) {
        arr[i] = arr[i - 1];
    }

    // Insert element
    arr[pos - 1] = value;
    n++; // Increase size

    // Print updated array
    printf("Array after insertion:\n");
    for (i = 0; i < n; i++) {
        printf("%d ", arr[i]);
    }

    return 0;
}
