How to implement imitation of clicks in the program?

Question

C++ / C#

Hi all!
There is a task: you need to run the program, and simulate a cycle of mouse and key clicks. Is it possible to do it with a bat file? Or maybe in c#?
Or there are other options - they are also interested. I would really appreciate links and advice.
