This site does not do laboratory for students, so I will give only a part of the code responsible for creating and adding a line to the ListBox.

This is how we create a ListBox that will contain the lines:

 hListBox = CreateWindow(TEXT("listbox"), NULL, WS_CHILD | WS_VISIBLE | LBS_STANDARD | LBS_HASSTRINGS, 7, 35, 300, 200, hWnd, (HMENU)(1), (HINSTANCE)GetWindowLongPtr(hWnd, GWLP_HINSTANCE), NULL);

And this is how we add a line to the ListBox:

 TCHAR string[] = TEXT("просто строка для примера"); SendMessage(hListBox, LB_ADDSTRING, NULL, reinterpret_cast<LPARAM>(string));

Then, I hope, you will figure it out yourself, if you still have questions, ask.
