for(int n = 0; n < 10; ++n, printf("%d\n", n)) ; // null statementIf the execution of the loop needs to be terminated at some point, a break statement can be used anywhere within the loop-statement. The continue statement used anywhere within the loop-statement transfers control...
C++20引入了范围for循环(Range-based for loop),可以方便地遍历容器(如数组、向量、列表等)和迭代器范围。 以下是一个简单的示例,演示如何使用范围for循环遍历数组: c复制代码 #include <iostream> #include <array> int main() { std::array<int, 5> a = {1, 2, 3, 4, 5}; // 使用范围for循环遍...

for 循环 rof 循环结束 break 跳出循环 continue 重新循环 local 设置局部变量 用法与set类似 #cpphtml介绍 cpphtml 语言必须包含在中,否则翻译器不会解析 定义一个变量:cpphtml没有变量类型,所有变量都是全局变量,全局可用 ##定义变量方式: 最简单的形式:set @a,10,定义了变量a,并初始化为10 变量初始化变量:...
switch on 类型:相当于自带break,不会执行两条输出语句。 if:branch 分支 select:选择 汇合 并发:sequence 循环:a)输出引脚Loop Body和Completed等同于 for(){循环体} 循环完毕 b)reverse 倒叙循环 while:while loop for:for loop 输出引脚Index可以显示当前是第几个循环 ...
