Thread: Liitle help with boolean expressions

Well as you can tell im a noob when it comes to programming but I want to learn and am a little confuzed.Hope somebody aint to busy and can help me out.

A. !( 1 || 0 ) ANSWER: 0
B. !( 1 || 1 && 0 ) ANSWER: 0 (AND is evaluated before OR)
C. !( ( 1 || 0 ) && 0 ) ANSWER: 1 (Parenthesis are useful)

Im reading the lesson 2:If statements and dont get it much.

The one I have trouble with is C.So if NOT is first right then the first 1 would evaluate to 0 hence false and then well it could not be true.

Feel so nooby lol hope somebody can help and pardon my typos main language is spanish...THX

Code:

C. !( ( 1 || 0 ) && 0 ) ANSWER: 1

When you evaluate boolean algebra, know what operations take precedence and work from the inside out, just like in math.

Code:

!(( 1 || 0 ) && 0 ) =
!((1) && 0 ) =
!(0) = 
1

Ah ok know I get it...thanks for your help really appriciate it
