There a several languages that don't have any Object Orientation support, being more logic based instead.

I suppose you could get away without a boolean type if you just used an integer instead (or a byte, depending on the language's implementation of types. A byte would usually be about equivalent to a bool, because of how it gets stored in memory). Heck, I once used an integer to store several different boolean values at once, purely to keep the size of data files down.

... TECH HERESY.
No, no, cool, but how?

A discussion with a friend led me to digging up this old video. His eyes snapping wide open in realization never ceases to amuse me.

I assume using each bit of the integer as its own boolean. It's a pretty common idiom, actually, when space is at a premium and you just need to have a shitload of flags. Take an embedded systems course somewhere if you ever have the chance, it's quite fun.

I will certainly think about that next course selection.

Indeed, C doesn't have any bools or bitfield structs by default, so your equivalents are usually chars/ints (depending on how much space you have to spare) and then any of the int types for use as a bitfield.

And I'll second that fun with an embedded systems course, I'm taking one right now (though the lowest level sort of electrical engineering stuff with circuits can get a little painful at times ).

C++: set up an enum, e.g:

enum
{
   flag1 = 1,
   flag2 = 2,
   flag3 = 4
   ...
   flag8 = 128
};

Then you check e.g. "if (flags & flag1)" checks flag1 of the "flags". To set a bit, used "flags &= flags1"

So with this you can easily store 8 bools in 1 byte, or 32 bools in 4 bytes. It could potentially be slower, since you have to use the bit operators to get the value, but it could be much faster in some circumstances. Less memory needed means less memory reads, and the bit operations could allow you to do complete sets of "if" statements (relying on multiple bits) in one CPU clock cycle. eg. if you have to check whether any of a set of conditions are true, then packing all the flags into one byte means the check can be one cpu instruction rather than a loop or 8 if statements.

Heh.  We'll take back our Internet yet...

[Helgoland]

All I can say is: Eh, we've been through worse.

[Akura]

Okay, I think I have to stay away from the Touhou videos now.

[KingofstarrySkies]

Never played touhou and I'm dying help

Pretty sure I heard that before as a phoenix wright clip, heh.

[Baffler]

Can someone please explain WTF exactly is Touhou? I watched those two videos and don't have the foggiest idea what I'm looking at. Is it some kind of parody that I wouldn't get without being familiar with the original?

[Graknorke]

Touhou is an anime bullet hell game. It has a massive fandom that makes fanworks in pretty much every conceivable medium because ???

[Aklyon]

Its a bullethell series full of girls wearing hats, made by a japanese guy who is much better at music than art. But since it has the massive fandom Grak mentioned, you get both in ridiculous amounts.
