Why doesn't my SFML program work?

[Servious]

I'm trying to make a program that draws d circles onto the screen randomly with random color, radius, etc. All it does is glitch up when I try it, help please! I'm using Code::blocks with minGW and SFML 1.6.

#include <SFML/Graphics.hpp>
#include <iostream>
#include <stdlib.h>
#include<time.h>

using namespace std;

int main()
{
    srand(time(NULL));
    int d = 0;
    bool fff = false;
    float vars[10];
    cin >> d;
    sf::RenderWindow App(sf::VideoMode(800, 600, 32), "SFML Graphics");
    while (App.IsOpened())
    {
        sf:: Event Event;
        while (App.GetEvent(Event))
        {
            if (Event.Type == sf::Event::Closed)
            {
                App.Close();
            }
        }
        for (int i = 0; i < d && !fff; i++)
        {
            vars[0] = rand( ) % 800 + 1;
            vars[1] = rand( ) % 600 + 1;
            vars[2] = rand( ) % 20 + 1;
            vars[3] = rand( ) % 255 + 1;
            vars[4] = rand( ) % 255 + 1;
            vars[5] = rand( ) % 255 + 1;
            vars[6] = rand( ) % 10 + 1;
            vars[7] = rand( ) % 255 + 1;
            vars[8] = rand( ) % 255 + 1;
            vars[9] = rand( ) % 255 + 1;
            App.Draw(sf::Shape::Circle(vars[0], vars[1], vars[2], sf::Color(vars[3], vars[4], vars[5]), vars[6], sf::Color(vars[7], vars[8], vars[9])));
        }
        fff = true;
    App.Display();
    //App.Clear();
    }
    return EXIT_SUCCESS;
}
