如果你真的想使用 switch 语句,你可以将 mark 除以 10 并让 case 10 和 case 9 等于 A,然后你可以在 case 8 到 case 5 中放置 if 条件语句,default 情况下为 f。 - kimo 0 不幸的是,Java没有像Javascript一样的switch-ranges,因此获得所需结果的一种方法是将mark除以10并进行四舍五入(例如8.5变为...
if the condition is true (execute if block) otherwise execute else block if the condition is false. But there is one more use case in the conditional statements. What if we want to put up one more check once the"if "condition fails and not execute the else statement directly?
IfStatementConditional:通过for循环来控制多个LED灯 If声明条件:使用一个‘if 声明’,通过改变输入条件来改变输出条件 Switch Case:怎样在非连续的数值里选择。 Switch Case 2:第二个switch-case的例子,展示怎样根据在串口收到的字符来采取不同的行为 While 声明条件:当一个按键被读取,怎样用一个while循环来校准一...
In VBA Switch Case, when we need to logically check or analyze a condition and execute the different lines of codes based on the same, we use IF-Else conditional statement. Similarly, there is one more statement Switch Case which is more widely known as Select Case statement which can check...
