While vs Do While Let's consider the previous while loop boolean trigger example. If I had initialized the value of keepGoing as false, the code in the while loop would have never executed and only the word "Stopped" would have been written to the console. However, if I were to initial...
Do While count < 5 Console.WriteLine("这行代码不会执行,因为初始条件为假") count += 1 Loop Console.WriteLine("循环结束") 输出: 循环结束 Do...Loop While 示例 vb Dim count As Integer = 10 Do Console.WriteLine("这行代码会执行一次,因为条件检查在循环结束后") count += 1 Loop While count...
在Visual Basic (VB) 中,Do While 循环是一种用于重复执行代码块的控制结构。它会在条件为真时继续执行循环体。Do While 循环有两种形式:一种是在循环开始时检查条件,另一种是在循环结束时检查条件。这两种形式分别称为 Do While...Loop 和 Do...Loop While。 1. Do While...Loop 在这种形式中,循环体在...
The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.Syntax do { // code block to be executed } while (condition); ...
C 循环 不像for和while循环,它们是在循环头部测试循环条件。在 C 语言中,do...while循环是在循环的尾部检查它的条件。 do...while循环与 while 循环类似,但是 do...while 循环会确保至少执行一次循环。 语法 C 语言中do...while循环的语法: do{statement(s);}while(condition); ...
SystemVerilog while and do-while loop 两者都是循环构造,只要给定条件为真,就会执行给定的语句集。whiledo while 循环首先检查条件是否为true,如果条件为true,则执行语句。如果条件被证明是假的,则循环就在哪里结束。while 循环首先执行一次语句,然后检查条件是否为true。如果条件为true,则执行该语句集,直到条件变为...
Here is an example of an infinite do...while loop. // infinite do...while loop int count = 1; do { // body of loop } while(count == 1); In the above programs, the condition is always true. Hence, the loop body will run for infinite times. for vs while loops A for loop ...
Do While...Loop 语句是条件为True时循环 Do until...Loop 语句是直到条件变成True时才停止循环 如果事先知道循环次数,应该使用For循环,据说它比Do循环速度快 不知道起点和终点,需要在循环内计算结果出来以后才能判断是否该终止循环的,用Do Loop循环。反之,如果很明确需要循环计算的次数,则用For……Next……计量循...
在Visual FoxPro的**DO WHILE...ENDDO**循环中,`LOOP`语句的作用是立即终止当前循环体的剩余代码,回到循环开始(即`DO WHILE`语句处),重新判断循环条件以决定是否继续下一次循环。 1. **选项A**正确。`LOOP`的作用正是转移到`DO WHILE`开启下一次条件判断和可能的循环,类似其他语言中的`continue`。 2. **...
Do…Loop循环 功能:当循环“条件”为真(While条件)或直到指定的循环结束“条件”(Until〈条件〉)为真之前重复执行“循环体”。 形式1: Do [While| Until〈条件〉] [〈循环体〉] [Exit Do] Loop 形式2: Do [〈循环体〉] [Exit Do] Loop [ ...
