title: equivalent LinkedHashmap in C++?
body: <p>I have a Java program that I want to convert it to C++. So, there is a <code>Linkedhashmap</code> data structure used in the Java code and I want to convert it to C++. Is there an equivalent datatype for <code>LinkedHashmap</code> in C++?</p>
  
  <p>I tried to use <code>std::unordered_map</code>, however, it does not maintain the order of the insertion.</p>
