Cleanest way to manage unique objects in C++? (lemmy.world)

Hello, I would like to store these http headers in classes:

Host: developer.mozilla.org
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:50.0) Gecko/20100101 Firefox/50.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate, br
Referer: https://developer.mozilla.org/testpage.html
Connection: keep-alive
Upgrade-Insecure-Requests: 1
If-Modified-Since: Mon, 18 Jul 2016 02:36:04 GMT
If-None-Match: "c561c68d0ba92bbeb8b0fff2a9199f722e3a621a"
Cache-Control: max-age=0

As you can see, many have unique data (numbers, strings, list of strings). I would like to:

store a header name
store list of possible options for that header (or store if it's a number)
read an input header and store and return the found option / list of options / number
make adding new types of headers as easy as possible

Is making hard coded classes for every type of header viable? How would this be done in the cleanest way possible?

Thank you for your advice, I've experimented with python, but I couldn' really read and understand how more complex examples work. I tried to implement backpropagation shown in a python example and couldn't, because it wasn't clear what type each variable was. I like C++ mutch more and I think I'm not a beginner at this point. Would you mind answering how important do you think are these coding projects for getting a job?

Every personal project is good as long as you try to make it professional. It doesn't need to be perfect but you can show that you made an effort to clean your stuff. I'm biased because I've been doing C++ for a long time, but every language is worth it. Also what I'm saying may be specific to my location and kind of job, but I tend to think it's kind of universal. To get a job, you need to show that you have a broad view of the software ecosystem.

For example for C++, you can do:

C++ code, maybe built with CMake or SLN because those are universal tools
linter and formatting (clang format, cppcheck, SonarLint, etc.)
good commits and branching strategy
some comments in your code
some documentation
unit-tests
maybe some scripts in Python for the CI
use a package manager like Conan or VCPKG because any company will pick random libraries all over the internet, you can't do everything from scratch

I think it applies to every language, just change C++ to any other language but the other bullet points don't change. And if you have some code to review, post it here and we'll read it like a real "merge request," it can be interesting.

Thank you for this useful advice, I will make sure my project follows your suggestions!
