Answer 1

lol brother it is a question which says solve this logical expression and deduce answer. ok now the question is how to solve the above expression. brackets have highest precedence in operators so first we solve the expression inside the bracket in your case ( a == !b) then the rest expression. if you really want to learn this please read logical operators section of C + + course

Answer 2

1. replace values (true ==! false) && true
2. evaluate what's in the brackets.
(true ==! false)
(true == true) // not false
(true) // yes, true does equal true. both sides
are equal
3. now we have
true && true // both conditions are true, so
4. true
