[C++ Classes and Inheritance] Why do we have them?

As someone who is intermediately fluent in Bash, Python and VB; I'm used to the scripting languages, it's been a bit of a curve with a compiler but I think I'm catching on. I have yet to finish the course but I'm in the middle of inheritance and polymorphism. This is a lot of assumptions I am writing below, so the point I want to get to here is: Is anything that I am saying, correct, close, not correct at all? I have yet to start a C++ project but understanding why I am being taught classes I asked myself: Why do we use them? A couple of possible answers that came to mind is automating object "clean up" so to say. Now this is a bit tricky since I don't fully understand it yet but when a program no longer needs something in memory that object that is sitting in the memory register needs to be deleted. Out of context I see that classes and inheritance allows that to be easily automated. I'm very used to just writing python functions all over the place until it eventually becomes a patchwork of passing arguments through one another. So a second theory is classes allow for a lot of organization. Correct me if I am wrong. Edit: I'm used to scripting languages cleaning up the mess in memory for me at the expense of performance. Now that I'm introducing myself to compilers, I now have to keep memory/dynamic memory in mind. Is this the main concept that classes and inheritance help with?

it there to reduce the errors in programmes even it very easy to acesd you can know when learn the basics of c++ clearly
