R12 Find first occurrence of an element (Recursion) Program Code

#include <stdio.h>

int firstOccurrence(int arr[], int n, int target, int index) {
    if(index == n) {
        return -1;
    }

    if(arr[index] == target) {
        return index;
    }

    int position = firstOccurrence(arr, n, target, index + 1);
    return position;
}

int main() {
    int arr[] = {5, 3, 8, 3, 9, 8, 2};
    int target = 8;
    int pos = firstOccurrence(arr, 7, target, 0);
    if(pos != -1)
        printf("First %d at index %d\n", target, pos);
    else
        printf("%d not found\n", target);
    return 0;
}
