Only first For loop called

I have two for loops that add subviews to the view. The first one adds all the subviews, but the second for loop is not even executed! Whats Up?

- (void)createBoxes
{
    for (int i; i<5; i++) {
        GameBox *box = [[GameBox alloc] initWithFrame:CGRectMake((i * 64) + 7, 50, 50, 50)];
        [self.view addSubview:box];
    }
    for (int e; e<5; e++) {
        GameBox *box1 = [[GameBox alloc] initWithFrame:CGRectMake((e * 64) + 7, 107, 50, 50)];
        [self.view addSubview:box1];
    }
}

Proper way would be to initialize variables : 

int i = 0;
int e = 0;

Otherwise you never know which value you'll get.

Why are you not initialising your loop variables? These are not standard for loops at all.
