1. 解释lambda表达式中的capture list是什么 在C++中,lambda表达式是一种可以捕获其所在作用域内变量的匿名函数对象。Lambda表达式的捕获列表(capture list)用于指定哪些外部变量将被捕获到lambda表达式的内部作用域中,以及是以什么方式(值捕获或引用捕获)进行捕获。捕获列表可以是空的,也可以包含一个或多个变量名,前面可以
早期的 C++ 更偏重于结构化和面向对象编程,而随着 Lambda 的加入,它开始融入了函数式编程的元素。这种转变使得 C++ 程序员可以更灵活地处理函数,尤其是在 STL(标准模板库)中。Lambda 表达式的引入,展示了 C++ 对于编程范式多样性的包容和对效率的追求。 错误 使用Lambda 表达式时,最常见的错误是捕获列表(capture ...
