Here is an example of Do While loop in JavaScript. var i=0; do { document.write(i+"<br>") i++; } while (i <= 5) In the above code condition is checked at the end of the loop only. Here also we can use break st
Let's look at an example that shows how to use a do-while loop in JavaScript. For example: var counter = 1; do { console.log(counter + ' - Inside do-while loop on TechOnTheNet.com'); counter++; } while (counter <= 5) console.log(counter + ' - Done do-while loop on Tech...
JavaScript 中的循环用来将同一段代码执行指定的次数(或者当指定的条件为 true 时)。实例 While 循环 利用while 循环在指定条件为 true 时来循环执行代码。 Do while 循环 利用do...while 循环在指定条件为 true 时来循环执行代码。在即使条件为 false 时,这种循环也会至少执行一次。这是因为在条件被验证前,...

JavaScript while 循环是 JavaScript 中最简单的循环,下面的例子利用 while 循环输出1到10。do while 循环和 while 循环非常相似,其区别只是在于 do while 保证必须执行一次,而 while 在表达式不成立时则可能不做任何操作
Example of do while LoopThe following program prints the Hello world message five times.Open Compiler #include <stdio.h> int main(){ // local variable definition int a = 1; // while loop execution do{ printf("Hello World\n"); a++; } while(a <= 5); printf("End of loop"); ...
