In this tutorial, you learned how to usewhileloops anddo whileloops. These loops can be used to keep iterating through a code block until some condition is met, even without knowing exactly how many time you want the code to run. You learned that ado-whileloop will always execute at lea...
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 = -...
Do While Loop This makes use of keywords ‘Do’ and ‘While’. This can further be divided into2 casesdepending upon the placement of the ‘Do’ and ‘While’ keywords. In the first case, Do and While are used in the beginning of the loop and in other cases, Do is used in the be...
than while loop. Here the condition is checked at the end of the loop. So even if the expression isFALSEthen also once the statements inside the loop will be executed. This is the basic difference between do while loop and while loop. Here is an example of Do While loop in JavaScript....
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... }
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 sameB.while循环比do…while循环执行效率高While is more efficient than do-whileC.while循环是先循环后判断,所以循环体至少被执行一次The While loop does the loop first then..
do-while循环和while循环的区别是:do-while循环体至少被执行一次。()此题为判断题(对,错)。请帮忙给出正确答案和分析,谢谢!
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...
You can easily convert a while loop into a do-while loop and vice versa. However, there are certain key differences between the two.The obvious syntactic difference is that the do-while construct starts with the do keyword and ends with the while keyword. The while loop doesn't need the ...
