Could someone explain Booleans?

Question

It didn't really explain it all that well :(

Answer 1

Boolean is a binary variable with two possible values true(1) or false(0).

Answer 2

Boolean variables are simply a switch. it is either on or off.

If you have a game with a locked door. trying to open it could check a boolean variable.

hasKey = True .... Door Opens
hasKey = False ... Door doesn't open

If you have a while loop, you generally have a boolean variable to run and stop it.

running=True;

while(running==True){
//Do something until running==False
}

I made TicTacToe the other day. I used booleans for each square to check if it was available for a move choice. Also used one to track if the game had a winner. If winner=True I don't allow any more moves until you hit reset. There are endless uses for boolean variables
