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...
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...

loops are very similar toloops, except the truth expression is checked at the end of each iteration instead of in the beginning. The main difference from regularwhileloops is that the first iteration of ado-whileloop is guaranteed to run (the truth expression is only checked at the end of ...
The do/while loop is a variant of the while loop. This loop will execute the code block once, before checking if the condition is true, then it will repeat the loop as long as the condition is true.Syntax do { // code block to be executed } while (condition); ...

In JavaScript do while loop executes a statement block once and then repeats the execution until a specified condition evaluates to false.
1. Print Numbers Using Do-While LoopWrite a C program to print numbers from 1 to 10 and 10 to 1 using a do-while loop. Sample Solution:C Code:#include <stdio.h> int main() { int i = 1; // Initialize the loop control variable to 1 // Print numbers from 1 to 10 printf("...
C语言的do-while语句的两种写法 while循环和for循环都是入口条件循环,即在循环的每次迭代之前检查测试条件,所以有可能根本不执行循环体中的内容。C语言还有出口条件循环(exit-condition loop),即在循环的每次迭代之后检查测试条件,这保证了至少执行循环体中的内容一次。这种循环被称为do while循环。
