Can you promote on r/cpp?

No rule mentions promotion None of its rules mentions self-promotion. That is not permission: read every rule, say plainly that it's yours, and make the post useful on its own.

Discussions, articles and news about the C++ programming language or programming in C++.

All 6 rules of r/cpp
  1. NO AI CONTENT
    AI-generated posts and comments are NOT allowed in this subreddit. DON'T use AI to "polish" or translate your words. We WILL notice. We MAY ban you without warning.
  2. Question/Help Posts
    Questions and help posts are off-topic for this subreddit. Use r/cpp_questions, r/cscareerquestions, or StackOverflow instead.
  3. Project Posts
    Personal projects written in C++ should be shared in the pinned "Show and Tell" post. Only major, established libraries/tools used by C++ programmers are eligible for top-level posts (e.g. Clang, GCC, MSVC, Boost, fmt, if you’re not sure then send modmail). NO BUILD SYSTEMS.
  4. Other Languages
    Posts about other languages (e.g. Carbon, Rust, Val, etc.) are off-topic *unless* there is substantial content directed at C++ programmers writing C++. That is, either posts about interop from the C++ side, or posts about interesting ideas *from* another language that can be applied *to* C++.
  5. Job Posts
    Employers looking for C++ developers and individuals looking for work must use the pinned "C++ Jobs" post.
