For loop: It allows users to execute a block of code a specific number of times. While loop: It allows users to execute a block of code if a specific condition is true. Do-while loop: This allows users to execute a block of code at least once and then repeatedly execute it if a ...
Thus, it is more straightforward to use ado...whilewhen you don't know the initial state of the variables for the while loop, or if the stop condition or initial state depend on calculations you have to do inside the loop itself. ...
So in the doCheck you could do like: function doCheck(e:MouseEvent):void { var sel:Boolean = true; for(var i:int = 0; i < checks.length; i++){ if(!checks.visible){ sel = false; break; } } if(sel){ trace("all selected"); } } Votes Upvote Translate Tra...
for ((a=0; a<=$num; a++)) do sum=$(($sum + $a)) done echo "the sum is ==> $sum" exit 0 错误如下: Syntax error: Bad for loop variable 分析: 从 ubuntu 6.10 开始,ubuntu 就将先前默认的bash shell 更换成了dash shell;其表现为 /bin/sh 链接倒了/bin/dash而不是传统的/bin/bash。
do echo $i; done 如果会报错,没有则跳过: Syntax error: Bad for loop variable 原因:代码对于标准bash而言没有错,因为Ubuntu为了加快开机速度,用dash代替了传统的bash,是dash在捣鬼。 解决方法:取消dash dpkg-reconfigure dash 出现弹框,选择NO 参考原文详情,解决报错: ...

can be used in ways that affect algorithm efficiency. for example, choosing an appropriate loop type or optimizing conditional branches can improve algorithm performance. it is important to understand the capabilities and performance characteristics of the programming language and its syntax when designing...
The continue statement is placed within the body of a loop, such as a for loop, while loop, or do-while loop. This can be executed with the help of if-else in C++. When encountered, the continue statement immediately stops the current iteration of the loop. Control then jumps to the ...
