int k = 0;
k = k++;

After both lines execute, what is k equal to?

Apparently, the answer depends on a number of things. In Java, k is 0. In C, it may be 0 or 1 depending on your compiler!

Bonus points if you can explain why.

1. Started on the gslug mailing list, reading about a new keyboard layout. I continue to be drawn in to rumors that the QWERTY layout is a conspiracy to slow down typers, so hearing about a new keyboard layout called Colemak piqued my curiosity.
2. Progressed quickly from colemak.com to the Wikipedia entry on Colemak. Cool, Colemak is supposed to be easier to switch to than Dvorak.
3. The Colemak entry on Wikipedia mentions digraphs. I’ve heard of digraphs because I use them in Vim, but you can use them in C, too? Strange.
4. The digraph entry on Wikipedia also mentions trigraphs. Trigraphs!

Sheesh. Interesting, but talk about distracting. I sure hope it isn’t true that multitasking kills your brain.
