Using Boost adaptors with C++11 lambdas

Question

I tried to compile this code:

#include 
#include 
#include 

int main() {
             


        

Answer 1

With C++17 feature class template argument deduction you can wrap with std::function simplier, like this:

*boost::min_element(
    v | boost::adaptors::transformed(std::function(
        [](int i) { return -i; })));
