std::map find_if condition style confusion

Question

I\'d like to use std::find_if to search for the first element in my map that has a certain value in a specific element of its value structure. I\'m a little confus

Answer 1

For the lazy, use a C++17 auto lambda, then you don't need to be verbose with the type.

const auto it = std::find_if(myMap.begin(), myMap.end(), [&val](const auto &it) { 
      return it.second.x == val; // Comparing with the object
   }
);
