logical operators

&&
and - true only if all are true, false if only one is false:

true && true // = true
true && false // = false
false && true // = false
false && false // = false
||
or - true if only one is true, false only if all are false:

true || true // = true
true || false // = true
false || true // = true
false || false // = false
!
not so !true = false and !false = true

    Indeed. Computer programming is really automated logic, so understanding what you wrote here is really important.
