while循环和do...while循环的区别是___。The different between while loop and do-while loop is:A.没有区别,这两个结构任何情况下效果一样There is no difference, they are the same.B.while循环比do…while循环执行效率高While is more efficient than do-while.C.
While 循环语句 和do while循环语句 的分号不能丢 同样写个1加到5的案例 两者的区别do-while语句是一种后测试循环语句,即只有在循环体中的代码执行之后,才会测试出口条件。其实就是,代码在刚开始执行的时候,都是要先走一遍do循环体内的代码,然后在与while里面的条件进行判断,成立循环就一直继续下去,不成立就跳出...
Difference Between while and do...while Loop Thewhileloop differs from thedo-whileloop in one important way — with awhileloop, the condition to be evaluated is tested at the beginning of each loop iteration, so if the conditional expression evaluates to false, the loop will never be execute...
3. Difference between while Loop and do-while Loop The main difference between do-while loop and while-loop is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the statements within the do block are always executed at least once. int i = -...
3. Difference between while Loop and do-while Loop The main difference between do-while loop and while-loop is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the statements within the do block are always executed at least once. int i = -...

Loops in the VBScript means those statements in the code which can be repeated several times until any particular condition reaches to an end. This tutorial gives you a complete overview VBScript For Loop, Do Loop, and While Loop.
// This loop is iterated 5 timesfor(inti =1; i <=5; ++i) {// body of the loop} Here, we know that the for-loop will be executed 5 times. However,whileanddo...whileloops are usually used when the number of iterations is unknown. For example, ...
aThe difference between do-while and while is that do-while evaluates its expression at the bottom of the loop instead of the top. Therefore, the statements within the do block are always executed at least once, as shown in the following DoWhileDemo program: 之间区别,做当,并且,当是时,做...
Difference between while and do-while loop in C, C++, Java while 循环: while 循环是一种控制流语句,它允许根据给定的布尔条件重复执行代码。 while 循环可以被认为是一个重复的 if 语句。语法: while(booleancondition) { loop statements... }
