-From the above source code：the value of the variable `_bool` is `true`; `_bool1` is not`_bool`, which yields `false`; `_bool && _bool1` is `false`；`_bool || _bool1` is `true`；`_bool == _bool1` is `false`；and `_bool != _bool1` is `true`.

 **Important note：** The `&&` and `||` operator follows a short-circuit evaluation rule. This means that for an expression such as `f(x) || g(y)`, if `f(x)` is `true`, `g(y)` will not be evaluated.
