Good morning angel, sorry for replying your question so late
firstly, your code is good while I test it by using bccn->online parser: https://www.bccn.net/run/(choose c++)
-----------------------------------------------------------
and your problem maybe like this:

or you could also search it from the apple site:

//online parser: https://www.bccn.net/run/(choose c++)

#include <iostream>
#include <algorithm>

using namespace std;

int main(int argc, char *argv[])
{
    const int n = 6;
    int a[6] = {5, 12, 7, 2, 9, 3};
    //sort
    sort(a, a + n);
    //print
    for(int i = 0; i < n; i++)
        std::cout << a[i] << " ";

    return 0;
}

output sample:

2 3 5 7 9 12
