while循环和for循环都是先判断表达式，后执行循环体（本质上没太大差别）；而do while循环是先执行循环...
while是最基本的循环,它的结构为: while(布尔表达式){//循环内容} 只要布尔表达式为 true,循环就会一直执行下去。 实例 Test.java 文件代码: publicclassTest{publicstaticvoidmain(String[]args){intx=10;while(x<20){System.out.print("value of x :"+x);x++;System.out.print("\n");}}} 以上实例编...
Loops are used for repeating a set of statements multiple times. There are different types of loops in VBA: For Loop, For Each, Do While & Do Until loops.
do...while loop in CIt is an exit-controlled loop. It prints the output at least once before checking the condition. Afterwards, the condition is checked and the execution of the loop begins.do...while loop Flowchart Syntax do{ //code to be executed }while(test condition); The body ...
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...

故答案为:d 两种语句都是控制循环结构的,For 语句是用数字来控制循环次数的,而Do Loop语句则是根据条件来控制循环的.结果一 题目 For语句和Do Loop语句的共同点是( ).A.循环次数已确定B.循环次数不能确定C.当满足条件时跳出循环D.当不满足条件时跳出循环 答案 For语句可以进行精确的循环次数控制,而Do Loop...
The value of the counter variable increments by 1 on each iteration and the do loop will continue to iterate until its value is less than 10. When the value of the counter becomes 10 the while condition becomes false and the do loop will exit. iNumber = 10 counter = 0 Do While ...
