逻辑布尔运算符使用bool操作数执行逻辑运算。 运算符包括一元逻辑非 (!)、二元逻辑 AND (&)、OR (|) 以及异或 (^),二元条件逻辑 AND (&&) 和 OR (||)。 一元!(逻辑非)运算符。 二元&(逻辑与)、|(逻辑或)和^(逻辑异或)运算符。 这些运算符始终计算两个操作数。
A user-defined type can't overload the conditional logical operators&∧||. However, if a user-defined type overloads thetrue and false operatorsand the&or|operator in a certain way, the&&or||operation, respectively, can be evaluated for the operands of that type. For more information...

The consequences range from reduced shielding effects right up to short circuits whenever the sharp wire ends penetrate through the fleeces or foils into the cores. Here, a useful tip: If, after the insulation has been stripped off, the shield can be easily pushed back over the jacket, the...
