为了让大家有个明确的学习方向,请大家分享给有需要的人,谢谢!...一、while循环 一般形式:while(表达式)语句,其中语句就是循环体注意:只要循环条件表达式为真(即给定的条件成立),就执行循环体语句例子: ? 结果: ?...二、do...while循环一般形式: do 语
...在每次循环中,循环变量会被赋值为当前的数字,并执行循环体内的代码。...以下是while循的一般用法: while condition do # 执行循环体代码 done ``其中: - `condition` 是一个条件表达式用于控制循环是否继执行。...以下是一个示例,演示
The do-while loop in C++ refers to the kind of loop that ensures the implementation of the code body at least once, irrespective of whether the condition is met or not. 21 mins read When it comes to iterative programming, loops are a fundamental construct. In C++ programming language, the...

1. while Loop in C While loop executes the code until the condition is false. Syntax: while(condition){ //code } Example: #include<stdio.h> void main() { int i = 20; while( i <=20 ) { printf ("%d " , i ); i++; } } Output: 20...
while(condition); Note:The semicolon;after thewhilecondition is required! Do/While Example The example below uses ado/whileloop. The loop will always be executed at least once, even if the condition is false, because the code block is executed before the condition is tested. ...
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。
// The loop goes while x < 10, and x increases by one every loop for(intx = 0; x < 10; x++ ) { // Keep in mind that the loop condition checks // the conditional statement before it loops again. // consequently, when x equals 10 the loop breaks. ...
do-while 循环语句的循环体是由一对花括号{}包围起来的语句 块。循环体中的语句会被重复执行,直到循环条件为假时结束 循环。循环体至少会被执行一次,因为循环条件是在循环体之 后进行判断的。例如:``` do {// 循环体 statement 1; statement 2; ... statement n; } while (condition); ```在上面的...
