How to create & sign a transaction from c++ code

Hey y'all,

I hope you are doing well.

I'm trying to figure out how to create and sign a transaction from c++ code.
I know how to do this with cleos or eosjs. However, how can I do this in plain c++?

I searched a lot before opening the issue, but it looks like there are no examples out there.

An example from the transaction generator plugin:

Many examples in the unittests, for example:

Assuming you are using an a RPC endpoint, you need to supply proper JSON for the HTTP request. Use cleos --print-request to determine that. There are many stages, mutliple requests, including fetching data from the chain, etc. MIght also help to look at the cleos source code, as well.
