As seen in the previous example, the capture scope initializes member variables in the corresponding class. This means that we can also initialize member variables inside a lambda, which are only visible from inside the lambda:
|
Lambda function... |
...corresponding class: |
auto func = [c=std::list<int>{4,2}](){ for(auto v : c) std::cout << v;};func();// Output: 42 |
class Func {public: Func() : c{4, 2} {} auto operator()()const->void{ for(auto v : c) std::cout << v; }private: std::list<int> c;};auto func = Func{};func();// Output: 42 |
