Odd Results in Application Output Pane on simple C++ app

[t4w2]

If I change the code slightly, this appears to work. I'm not sure why, but there must be some kind of glitch with flushing cout on std::endl in Qt Application Panel.

#include <iostream>
 
using namespace std;
 
int main()
{
    int i;
 
    for (i=1; i<52; i++)
    {
        cout << i << "\n";
    }
    cout << endl;
    return 0;
}

#include <iostream>

using namespace std;

int main()
{
    int i;

    for (i=1; i<52; i++)
    {
        cout << i << "\n";
    }
    cout << endl;
    return 0;
}
