This example is functionally equivalent to the firstwhileloop example above and will result in an infinite loop. While vs Do While Let's consider the previouswhileloop boolean trigger example. If I had initialized the value ofkeepGoingas false, the code in thewhileloop would have never executed...
Do-While Loop do-while循环会先执行一次循环体,然后再检查循环条件是否为true。如果条件为true,则继续执行循环体,否则跳出循环。do-while循环至少会执行一次循环体。 while True: # 执行循环体 if (not condition): break 例子: count = 5 do: print(count) count += 1 while count < 5 # 输出结果:5 ...
While Loop vs Do-While Loop 在许多编程语言中,有两种基本的循环类型可用于重复执行语句块:while循环和do-while循环。这些类型的主要区别在于它们的执行顺序和循环条件的检查时间。 While Loop while循环是一种预测试循环,这意味着在循环的每一次迭代之前,循环条件都会被检查。只有当条件为“真”时,语句块才被重复...

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-loop 回答3 Stack Overflow用户 回答已采纳 发布于 2021-01-24 06:47:02 C语言被设计成即使是非常简单的编译器也能产生相当高效的机器代码。虽然可以将while(condition) {block};表示为if (condition) do {block} while(condition);或将do {block} while(condition);表示为if (1) {block} do {block...
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
