glock.c?

croke ?

'i=x/2/(3+2);dx=x/2%(3+2);'

Why not i=x/10;dx=x/2%5;?

(5-(y-5)/2-1)*3

Basically 12-(y-5)/2*3

Also k=10; will save some space and x=y=0; instead of x=0,y=0;

Ну кисонька, милая, ну ещё рюмашечку

I can't believe nobody yet suggested to assign the values of d with braces like so:

d[8] = {
    tm->tm_hour/10,
    tm->tm_hour%10,
    [...]
}

Instead of assigning by index.

I thought about it. I didn't touch C for almost 10 years, but I believe this will work only with dynamic array, witch need a little more typing to work.

it's too small now i have to add copious amounts of padding just so the clock isn't cropped 😔
