The PHPdo-whileloop is a control structure that executes a block of code at least once, then repeats while a condition remains true. Unlike regular while loops, do-while checks the condition after each iteration. Basic Definitions Thedokeyword starts a do-while loop that always executes its b...
In our example below, we skip the iteration wheneverxequals3. <?php$x=1;do{if($x==3){$x++;continue; }echo"The value of x is ".$x."";$x++; }while($x<=5);echo"Exited the do while loop.";?>Copy As you can see in our output below, we did not print any data when the...
Example Run this code» <?php$i=1;do{$i++;echo"The number is ".$i."";}while($i<=3);?> 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...
在PHP中,do-while循环和while循环都是用于重复执行代码块的循环结构。它们之间的主要区别在于循环执行的时机。 do-while循环会先执行一次代码块,然后在检查条件是否满足之前继续执行循环。换句话说,do-while循环保证至少会执行一次代码块。 而while循环在每次循环开始之前都会先检查条件是否满足,如果条件不满足,则循环体...
Example 1: Check Armstrong Number Using do-while Loop=begin Ruby program to check whether the given number is Armstrong or not using a do-while loop =end puts "Enter the number:" num = gets.chomp.to_i # Store the original number for comparison temp = num sum = 0 # Implementation of...
Working of while loop Example 1: while loop // Print numbers from 1 to 5 #include <stdio.h> int main() { int i = 1; while (i <= 5) { printf("%d\n", i); ++i; } return 0; } Run Code Output 1 2 3 4 5 Here, we have initialized i to 1. When i = 1, the te...

Example int i = 0;do { cout << i << "\n"; i++;}while (i < 5); Try it Yourself » Do not forget to increase the variable used in the condition, otherwise the loop will never end!Exercise? What is a key difference between a do/while loop and a while loop? A do/while...
using a simple while loop: And that is when the check condition is made. In a do--while loop, the test condition evaluation is at the end of the loop. This means that the code inside of the loop will iterate once through before the condition is ever evaluated. This is ideal for ...
var i=0; do { document.write(i+"") i++; } while (i <= 5) In the above code condition is checked at the end of the loop only. Here also we can use break statement to come out of the loop. Here is the example var i...
