while (condition) { // code block to be executed } 在这个语法中,condition是一个布尔表达式,代表循环条件。code block是需要重复执行的代码块。 While-loop的优势在于它可以根据条件动态地控制循环次数,使得程序能够灵活地处理不同的情况。它常用于需要重复执行某段代码直到满足特定条件的情况下,例如遍历数组、处...
The while loop first checks the condition, and then decides what to do. If the condition proves to be false, the instructions in the code block will not be executed. while (condition) { //Instructions be executed } Example A basic example of the Java while loop. Other supporting code ...
The code implementing thewhileloop is in theex_while_loop_ML_stepfunction inex_while_loop_ML.c: /* Model step function */ void ex_while_loop_ML_step(void) { int32_T num_iter; boolean_T flag; boolean_T func_flag_0; /* MATLAB Function: '<Root>/MATLAB Function' */ func_flag_0 ...
-> leave loop_label; -> end if; -> end loop; -> end;// Query OK, 0 rows affected (0.00 sec) 从上面这个例子可以看出,使用LOOP编写同样的循环控制语句要比使用while和repeat编写的要复杂一些:在循环内部加入了IF……END IF语句,在IF语句中又加入了LEAVE语句,LEAVE语句的意思是离开循环,LEAVE的格式是...
A basic example of the VB.NET While loop. Other supporting code was removed to improve readability and keep the code short. Dim x As Integer While (x < 5) Console.WriteLine(x) x = x + 1 End While 0 1 2 3 4 As shown above, the while loop printed out all the numbers from 0 ...
The While Loop Thewhileloop loops through a block of code as long as a specified condition is true. Syntax while(condition) { // code block to be executed } Example In the following example, the code in the loop will run, over and over again, as long as a variable (i) is less th...
一、循环使用 mysql常见的三种循环方式:while、repeat和loop循环。还有一种goto,不推荐使用。 前提1、创建基本表结构 # 创建表结构 drop table if exists `test_table`; create table `test_table`( `id` bigin
VBA 中Do while Loop用法如下：VBA中如果不知道重复多少次，使用 Do...Loop 语句。Do...Loop 语句重复执行某段代码直到条件是 true 或条件变成 true。重复执行代码直到条件是 true使用 While 关键字来检查 Do... Loop 语句的条件。Do While i>10'some codeLoop 如果 i 等于 9，上述循环内的代码...
又和Alex老师学了一招,前面loop循环是0123456789,现在想要它loop循环只有偶数02468,可以把for i in range(10)括号内的数字改为(0,10,2),就成功了。 如果有人尝试了三次后,还想继续,要问用户是否继续时,该怎么办? 当最后一次循环count+1等于3时,就要做出一个判断, ...
