Newbie question, Need help to understand boolean
I am using the tutorial:
Cprogramming.com Tutorial: If Statements
I can't seem to grasp one thing in this tutorial. Maybe I am focusing on the wrong thing or something, but here it is.
At the end of the tutorial it is talking about Boolean operators.
How do you get the answers to that?
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)
I am trying to make my question as clear as I can.
How can you take !(1 || 0) and say the answer is 0 ?
Can someone maybe explain it in a different approach or something so that I can understand it?
Maybe how to evaluate that step by step?
I think I know this much:
! = NOT
|| = OR
NOT is evaluated before AND OR
AND = is evaluated before OR
I understand everything in the previous tutorial's. I just feel if I don't grasp this I will have problems understanding future things. I have written and manipulated beginner code from the previous tutorial's just fine.
