do{}while(1)语句使用的不多,因为也会需要在执行语句之后判断条件,会浪费单片机的资源。 4.goto语句 loop: //code goto loop; 实际的嵌入式开发中,很少使用goto语句,但是也可以使用goto语句编写死循环。 #include<iostream> using namespace std; int main() { //用goto实现infinite loops(死循环) A: cout...
Flowchart of while loop 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...
Let’s take a look at the example: First you must always initialize the counter before the while loop starts ( counter = 1). Then the while loop will run if the variable counter is smaller then the variable “howmuch”. If the input is ten, then 1 through 10 will be printed on the...
do-while循环或for循环必须包含花括号/* OK */while (is_register_bit_set()) {}/* Wrong */while (is_register_bit_set());while (is_register_bit_set()) { }while (is_register_bit_set()) {}如果while(或for、do-while等)为空(嵌入式编程中也可能是这种情况)，请...
do{ //code to be executed }while(test condition); The body of the loop executes before checking the condition. If the test condition is true, the loop body executes again. Again the test condition is evaluated. The process repeats until the test condition becomes false. Example: do...wh...
while (scanf("%ld",&num) ==1) 对于涉及索引计数的循环,用for循环更适合。例如: for (count=1; count <= 100; count++) 嵌套循环# 嵌套循环(nested loop)指在一个循环内包含另一个循环。嵌套循环常用于按行和列显示数据,也就是说,一个循环处理一行中的所有列,另一个循环处理所有的行。
#include<stdio.h>intmain(){int i=1,sum=0;loop:if(i<=100){sum+=i;i++;goto loop;}printf("Sum=%d",sum);return0;} 打印: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 Sum=5050 显然,此时求出了1-100的和。 三、while语句 ...

while循环语句 一、 循环结构的思想及意义: 循环结构的思想就是重复要做同样的事, 也就是程序中重复执行的语句, 我们只要控制好循环的 初值 ,条件 和步长 就可以轻松解决问题。 循环三要素: 初值 条件 步长 二、 while的基本格式*** (1)While它的格式变形如下:(流程图如右图所示: 当型循环结构) 表达式1...
In programming, a loop is used to repeat a block of code until the specified condition is met. C programming has three types of loops: for loop while loop do...while loop We will learn about for loop in this tutorial. In the next tutorial, we will learn about while and do...while...
