A. For loop is used for definite iterations while while loop is for indefinite iterations. B. For loop is faster than while loop. C. While loop can only be used with numbers while for loop can be used with any
while loop can run indefinitely C. for loop is more complex D. none of the above 相关知识点: 试题来源: 解析 B。本题考查 for 循环和 while 循环的主要区别。while 循环可以根据条件无限运行,而 for 循环通常有明确的循环次数限制。选项 A 不准确,不能说 for 循环总是更快。选项 C 不准确,不一定...
C# LOOPS: WHILE VS DO-WHILE May 06, 2019 by Bradley Wells 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 previous tutorials, you...
LoopDifference /*三种循环的区别。 1如果条件判断从来没有满足过,那么for循环和while循环将会执行0次,但是do-while的循环会至少执行一次。 2for循环的变量在小括号中定义,只有循环内部可以使用。while和do-while循环初始化语句本来就在外面,所以循环出来之后还可以继续使用。*/publicclassLoopDifference{publicstaticvoidm...
because you wrote : "while t<40" which does not include the 40, it self. But "for" contains the upper bound, which is 40. In other word, your first loop is done 4000 times, however, the "for" loop runs 4001 times. This may be the main result of difference that you are lookin...
A while loop in C++ is an example of an entry-controlled loop wherein the condition is checked at the entry of the loop. The loop runs until the condition is true, and the statements/ block of code inside the body of the loop are executed. The loop terminates as soon as the ...

while(condition); Note:The semicolon;after thewhilecondition is required! Do/While Example The example below uses ado/whileloop. The loop will always be executed at least once, even if the condition is false, because the code block is executed before the condition is tested. ...
We use FOR to iterate over a known range of values and WHILE to evaluate an expression. for (initialization; termination; increment) { statement(s) } while (expression) { statement(s) } The difference between WHILE and DO WHILE is that on WHILE it checks the condition first, than execute...
Do Loop While is an extended version of Do While Loop as it works in the same way but there is a slight difference while testing the condition. In Do Loop While, it runs one iteration of the loop before testing the condition that you have specified and if the condition is true it will...
