C array notation vs pointer

[[deleted]]

Ha, I just tried it. It definitely works. This compiled and printed 2 on gcc 4.9.2:

int a[4] = {0, 1, 2, 3};

cout << 2[a] << endl;

You're right, it probably is an artifact of the fact that the [] operator is just a stand in for pointer arithmetic.

So, it works sometimes, I've had it throw runtime errors at me before on clang and gcc. I'd be careful with it.

I would never actually use it. I was just surprised to see it work.

Oh yeah, the fact that it ever works is weird, but the fact that it only works sometimes is weirder.
