This tutorial will explain the difference between a While loop and a Do While loop in C#. You will learn when to use each type of iterative statement by working through practical examples. C# While Loop In prev
// infinite do...while loopintcount =1;do{// body of loop}while(count ==1); In the above programs, theconditionis alwaystrue. Hence, the loop body will run for infinite times. for vs while loops Aforloop is usually used when the number of iterations is known. For example, ...

Do While ?Loop Do While ... Loop 會驗算條件,如果條件為 True,就接著驗算條件之後的陳述式。 驗算結束後,此迴圈會繼續驗算條件,而如果條件為 True,又會再次驗算陳述式。 這個程序會繼續重複進行,直到條件為 False 時。 複製 Do While condition statements Loop Do Until ... Loop Do Until ... Lo...
In the previous tutorial we learned while loop in C. A do while loop is similar to while loop with one exception that it executes the statements inside the body of do-while before checking the condition. On the other hand in the while loop, first the con
更新:2007 年 11 月 Loop 陳述式含有 While 或 Until 子句,且對應的 Do 陳述式也含有類似的子句。迴圈的 Do 或 Loop 陳述式中,只有其中一個可以指定條件。 錯誤ID:BC30238 若要更正這個錯誤 移除Do 陳述式或 Loop 陳述式中的 While 或 Until 子句。 請參閱 參考 Do...Loop 陳述式 (Visual Basi...
do-while 循环是一种后测试循环(also known as exit-controlled loop):首先执行循环体中的语句,之后才评估循环的继续条件。与之对比的是 for 和 while 循环,它们都是先测试循环条件,然后再执行循环体,称为前测试循环(pre-tested loop)。在实际编程中,根据具体需求选择最合适的循环类型非常重要。
while(test condition){//code to be executed} If thetest conditioninside the()becomestrue, the body of the loop executes else loop terminates without execution. The process repeats until thetest conditionbecomesfalse. Example: while loop in C ...
Do...While 语句在条件保持为 True 时重复一个循环,但您有时可能希望代码在条件变为 True 之前重复自身。您可以按如下所示使用 Do...Until 语句: VB DimsumAsInteger=0DoUntilsum >=100sum = sum +10Loop 此代码与 Do...While 语句的代码类似,只是这次代码是计算 sum 变量,看它是否等于或大于 100。
