what is "bool"?

[c0d3Man15]

I haven't found anything in any of the books I've read, and I cant seem to find anything with google that gives a clear explanation of what it is, so what is bool? and how can I use it? A description of what it is and some examples of how to use it and stuff would be great, thanks in advance for any help.

"Bool" is short for "Boolean": http://en.wikipedia.org/wiki/Boolean_datatype

Then you're reading the wrong books. bool should always be mentioned in the first or second chapter when variables and data types are introduced.

A bool can only have two values, true or false.

strongdrink's comment ^.

If you typed in bool on google, the first result would be what Computergeek01 linked to. Learn to use Google, for it is a nice resource when you quickly need to look up something.

strongdrink hit the nail but since you're looking for an example ...

bool is a type just like int or char so you wud declare a variable of type bool.

bool x;
x = true; //or
x = false;

use can also use 1s and 0s, 1 for true, 0 for false.

practical uses? testing functions

write a function filled with code testing some calculation or whatnot then returning true if it passes or false if it doesnt.

Can I add something? I think boolean logic was invented by George Boole and hence the name credited to his honor ? :P

Thanks for all the help, I suppose having access to this nice forum has been making me lazy, normally I would just google something and eventually find what I was looking for, no matter what I was searching for, but I havnt been thinking to clearly lately, to much insomnia, and mix that with ADD and then throw in a ton of preCalc homework, and youve got yourself a very tired person who now has an even harder time focusing on stuff and has a somewhat fried brain from doing complicated math while very tired... anyways, again thanks all for the help :)
