当然，也可以反向而不是正向运行循环，或者使用1之外的循环计数器增量，甚至像while语句那样完全取消循环计数器。
One special feature of the break statement is that it breaks completely out of the loop, thereby skipping any else clause that follows the loop.
break语句的一个特殊特性是，它完全中断循环，并跳转到循环下面的任一个else子句。

As discussed in the previous article, the continue statement causes the containing loop to start the next iteration.

The WHILE statement defines a set of statements to be executed until a condition that is evaluated at the beginning of the WHILE loop is false.

When using this technique, the while (1); statement must be stripped at the client before using the JSON data to avoid an endless loop.
使用这种技术时，这个while(1)；语句必须在使用该JSON数据之前在客户端上剥离，从而避免无限循环。
This is actually what the statement looks like once the compiler converts it internally to a normal for loop.

Selecting any mapping statement in the Script Pane shows all source and target mappables referenced in the statement, such as mapping source, loop iterator, condition, where clause, and so on.
在Script窗格中选择任何映射语句，这将显示该语句中所引用的所有源和目标可映射对象，如映射源、循环迭代器、条件、where子句，等等。
The main method USES an enhanced for loop to iterate through the different primitives and a simple switch statement on the current instance to set the size value of each primitive.
main方法使用增强的for循环来迭代通过不同的原语，并在当前实例上使用一个简单的switch语句来设置每个原语的大小值。
The getopts command returns true if an option is found, so a common option processing paradigm uses a while loop with a case statement as in this example.
如果找到一个选项，则getopts命令返回true，因此常见的选项处理范例使用带case语句的while 循环，本例中就是如此。
The next statement in the loop body is a second if statement that tests whether the variable I is evenly divisible by 125, but this expression is preceded by the not operator.
循环体中的下一个语句是第二个if语句，它测试变量i是否能被125整除，但是该表达式前面加了一个not运算符。
A while loop within bash allows you to execute a statement a given number of times, or until a certain condition is met.
bash中的while循环可以重复执行语句一定的次数，或者一直执行到满足某一条件为止。
The second type of flow control statement in Python is the while loop, which executes a block of program statements while an expression evaluates True.
Python中的第二种流控制语句是while循环，它在一个表达式计算为True时执行一个程序语句块。
Oracle also allows cursors to be tightly bound to a looping statement, a construct called a cursor FOR loop.
Oracle还允许将游标与一个循环语句紧密地绑定在一起，形成所谓的游标FOR循环结构。
The while loop, as was the case with the if statement, supports an optional else clause containing a block of program statements executed when the expression is False.
while循环与if语句一样，支持一个可选的else子句，其中包含一个当表达式计算为False时执行的程序语句块。
When the FETCH cursor statement fails and does not find another row to retrieve, the value of SQLSUCCESS is set to 0 and the WHILE LOOP ends.
当FETCH游标语句失败并且没有找到另一个要检索的行，SQLSUCCESS的值被设置为 0 并且WHILE LOOP 结束。
This causes the break statement to be executed, breaking out of the loop.
这导致执行break语句，中断循环。
