Three types of loops are used in bash programming. While loop is one of them. Like other loops, a while loop is used to do repetitive tasks. The starting and ending block of the while loop is defined by do and done keywords in the bash script. The termin
In the above example the loop is terminated when x becomes 5. Here we use break statement to terminate the while loop without completing it, therefore program control goes to outside the while - else structure and execute the next print statement. Flowchart: Previous:Python For Loop Next:Pytho...
The while loop can be used in different ways to implement the functionality of the do-while loop. Generally, the while loop checks the condition at the beginning of the loop to start the iteration. So, if the condition is set to True, the while loop will work like the do-while loop. ...
每当你使用一个接受输入的语句时(在你的例子中是int input = kbd.nextInt(); ),java应用程序就在那里停止执行,并等待来自指定源的输入(System.in在这里),再次尝试执行代码,这次输入一个随机数,它将是循环开始后输入变量的值。同样,在这个游戏中,你应该把int input = kbd.nextInt(); 改为 int input = -...

SET @counter = 0; WHILE @counter < 10 DO -- 循环体代码 -- 可以是任意有效的SQL语句 SET @counter = @counter + 1; END WHILE; 上述代码中,首先使用SET语句初始化一个变量@counter,并将其赋值为0。然后使用WHILE关键字定义一个循环,条件为@counter < 10,即当@counter小于10时执行循环体内的代码。循...
