Storing a list of parameters that can be referred to by name

Question

Programming

There is a certain list of parameters in the form of a string set. To be clearer, it looks like a response header from a web server, i.e. format " parameter_name: value\r\n ". At least one parameter is stored.
The task is to store a list of parameters with their names and values, as well as to quickly search for the value of the required parameter by its name.
For example, there is a list: And there should be analogies of commands: I'm interested in ready-made solutions for organizing storage and retrieval. I have already considered several options: boost.property_tree - this library implements methods for working with xml, ini, info, json formats - there is no one suitable for me here. If you use this container, you will have to write your own parser. hash tables
параметр1: значение1\r\n
параметр2: значение2\r\n
getValueByName("параметр2");
addNewValueToList(param_list, "параметр37", "значение37");


- a table of correspondences is created by the name of the parameter. Based on this, you can figure something out, but I still don’t like something about this method;
storage in an array - this option is less interesting to me as the most raw. Here you will have to write all the functions yourself.

Tell me what should I choose. Can you suggest a better option.

Answer 1

Storage - hash tables (or std::map, if there are no performance problems).
Parsing is another matter.

Answer 2

I would also use hash tables - in g++ there is a hash_table class, in ms c++ it seems to be the same, but I'm not sure for sure.

Answer 3

Thanks to all. I will learn then hash tables. there seems to be no other choice. Parser, so be it, I'll write it manually then.

Answer 4

Actually store everything in mongodb, that's what it's for.
