Do you have experience working with the MFC library for C++ application development?

Yes, I have experience working with MFC (Microsoft Foundation Classes). MFC is a C++ class library that simplifies the creation of Windows GUI applications. It provides wrappers around the WinAPI, making it easier to work with windows, messages, dialogs, and other GUI elements.

Example of creating a simple window with MFC:

class CMyApp : public CWinApp {
public:
    BOOL InitInstance() override {
        CFrameWnd* pFrame = new CFrameWnd();
        pFrame->Create(NULL, _T("MFC Application Example"));
        m_pMainWnd = pFrame;
        pFrame->ShowWindow(SW_SHOW);
        pFrame->UpdateWindow();
        return TRUE;
    }
};

CMyApp theApp;

MFC is often used for classic Windows applications with an interface, where integration with WinAPI and performance are important.
