Trying to make a ball bounce across the render window - c++

Question

I am trying to make a ball bounce across the render window using SFML. I am trying to make the ball appear in a new random location each time as well. I cannot make the ball go infinitely though. When ever I play it and it spawns a new location it does not bounce off the render window though. I don't know how to make it do this.
#include <iostream>
#include <SFML/Graphics.hpp>
#include <stdlib.h>
#include <time.h>
using namespace std;
using namespace sf;
int main()
{
RenderWindow window(sf::VideoMode(1500, 800), "Bouncing Circle");
window.setFramerateLimit(60);
srand(time(NULL));
int randx = rand() % 1500 + 1;
int randy = rand() % 800 + 1;
int x;
int y;
int distance = 1500 - randx;
int distance2 = 800 - randy;
int BREAK = 1;
sf::CircleShape MyCircle(50);
MyCircle.setPosition(randx, randy);
MyCircle.setFillColor(sf::Color(500, 0, 0));
while (window.isOpen()) {
sf::Event event;
while (window.pollEvent(event))
;
{
if (event.type == sf::Event::Closed)
window.close();
}
x = randx;
y = randy;
for (int ii = 0; ii < distance and ii < distance2; ii++) {
x++;
y++;
MyCircle.setPosition(x, y);
window.draw(MyCircle);
window.display();
window.clear();
if (x == distance and y == distance2) {
for (int aa = 0; aa <= 650; aa++) {
MyCircle.setPosition(x, y);

x++;
y--;
window.draw(MyCircle);
window.display();
window.clear();
if (aa == 650) {
for (int pp = 0; pp <= 92; pp++) {
MyCircle.setPosition(x, y);
x++;
y++;
window.draw(MyCircle);
window.display();
window.clear();
if (pp == 92) {
for (int n = 0; n <= 570; n++) {
MyCircle.setPosition(x, y);
x--;
y++;
window.draw(MyCircle);
window.display();
window.clear();

return 0;
