You can do it with your determination.

half of the tasks do not compile, give an error. Why are you reporting on unsolved tasks? It was necessary to understand what the error was and eliminate it. And in the task I asked for screenshots of the code, not the text of the code.

Well, since I didn't use my system (PC) to run the code, because my system is faulty which I took for repair, I thought sharing the code would be helpful because screenshotting it via phone to share wouldn't be fully displayed. Thanks for your suggestions

the problem is different, the code doesn't compile, so you can't check if the program is correct or not. for example, you get an error on cout, then you should either write std::cout or at the beginning of the program write using namespace std
In other tasks, you compile a part of the code, not the whole program, and you see a message that there is no main() function, while it is required
