Where can I get interesting problems and ideas for C++?

Question

C++ / C#

Hello, I recently started learning C++. In a few days I got to OOP, but due to my zero fantasy, I could not come up with interesting ideas for practicing my knowledge. I didn’t find a normal solution to my problem on the Internet, because most of the projects are very difficult to complete (I want to learn how to practice my newly acquired knowledge, and not set impossible tasks, and then think for a few days, eventually score.) or too simple (For example, after the video task lessons like "try to create variables and then print them to the console."). I really want to find my middle ground, where I will not spend all my free time on solving any problem.

I can cite a recent case from my life as an example. I was asked to write a window application that renders a widget (HTML file). Due to the fact that I had no idea about windowed applications, I began to search the Internet for information on this subject. Still, there is a lot of garbage on the Internet and you need to be able to select it in order to get a normal result. For example, I started using WinForms, because I worked with them in C# a little. Then I got confused and mixed C# and C++ together and never got the result.

leetcode.com is a very interesting platform for both linear and non-linear puzzles. It is possible to implement the solution in different languages, the possibility of choosing the complexity of the task. Addictive :)
