C++11 lambda as member variable?

Question

Can lambda\'s be defined as class members?

For example, would it be possible to rewrite the code sample below using a lambda instead of a function object?

Answer 1

A lambda just makes a function object, so, yes, you can initialize a function member with a lambda. Here is an example:

#include 
#include 

struct Example {

  Example() {
    lambda = [](double x) { return int(std::round(x)); };
  };

  std::function lambda;

};
