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...
break continue return goto contract_assert Executes aforloop over a range. Used as a more readable equivalent to the traditionalforloopoperating over a range of values, such as all elements in a container. Syntax attr (optional)for (init-statement (optional)item-declaration:range-ini...
