Answer 1

Variable type. Can be true (1) or false (0). Stored in one bit.

Question 2

Boolean operations

Answer 2

And (&&), or (||), not (!)

Always enclose boolean expressions in parentheses so there isn’t any odd behavior due to order of operations. Boolean order of operations is not, and, or.

Question 3

Not (boolean operation)

Answer 3

Flips the bool (false becomes true, true becomes false). ! Is the not operator and comes before whatever it is flipping.

Question 4

And (boolean operation)

If two conditions are met, it returns true. && is the and operator. Using only one & is known as bitwise, which is not the same thing.

Question 5

Or (Boolean operator)

Answer 5

Is true if either condition is met. || is the or operator.

Question 6

Logical Operations

Answer 6

The computer reads not first, then and, then or.
