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...
Today, we’ll look at the first column: The functor. Functoris C++-speak for “anything you can call as if it were a function.” The functor could be an actual function, likeCoGetObjectContext, or it could be something that has an overloadedoperator(), such as a lambda. After the fun...

The value of the variable will be copied into the lambda, and will remain valid even after the local will have gone out of scope. Just to make sure this sinks in: had I assigned pn the address of local variable, I would have been in trouble again even after capturing pn by value: ...
Given int Variable = 42; []() { ++Variable; }; We get the warning Variable 'Variable' cannot be implicitly captured in a lambda with no capture-default specified [clang: lambda_impcap]. It would be nice to suggest adding Variable to the capture list....
