c programming

Write a function that prints the values in the array that appear once

Example: A = {4, 1, 2, 3, 4, 4, 5, 6, 2, 7}

Output: 1, 3, 5, 6, 7

#include <stdio.h>

void print_unique(int arr[], int size) {
    int i, j, count;
    for (i = 0; i < size; ++i) {
        count = 0;
        for (j = 0; j < size; ++j) {
            if (arr[i] == arr[j]) {
                count++;
            }
        }
        if (count == 1) {
            printf("%d ", arr[i]);
        }
    }
    printf("\n");
}

int main() {
    int arr[] = {4, 1, 2, 3, 4, 4, 5, 6, 2, 7}; // change this array to anything you want. this code will still work..
    int size = sizeof(arr)/ sizeof(int);
    print_unique(arr, size);
    return 0;
}
