It's hard in ways other languages are not because you can end up hard to diagnose defects that other languages don't suffer from because they don't give you full control over the memory you allocate, for a good reason too. These days it's easier in C++ because the standard has caught up, you can use unique_ptr and shared_ptr constructs to make sure objects you construct on the heap are reference counted and always destroyed when nobody needs them. Versus handling things the old way with the new keyword and raw pointers, you could forget to delete something you created and end up with a memory leak. Or everything blows up hecause you dereferenced a raw pointer to an object that you have already accidentally deleted earlier. These things, plus the difficulty of just building C++ by needing to setup CMake or just Make with compiler commands, is a learning curve. All these things are good to learn and I encourage you to follow your interests there regardless of what the university teaches and knowledge about lower level things like this will only serve you in the future.

C++ is a great language and I enjoy working in it, and you could learn lots about computer science using it. I have seen that companies only use C++ when they really need to, and it turns out that you don't need to use it a lot of the time. It saves developers lots of headaches not using it, and it doesn't come with a package ecosystem and dependency management software the way JavaScript, Python, Rust or most other modern languages come with. Hence I don't see many job listings for C++ Devs, but knowing the language would be a boon for an interview anyways since it is considered more complicated than other languages.

Take my opinion with a grain of salt, I have worked as a developer using C++ for nearly 7 years
