请帮我写出这样一段代码：使用C语言，只能使用C语言或windows函数，不能使用第三方图形库，实现导入图片并显示

以下是一个简单的使用 C 语言和 Windows 函数导入图片并显示的示例代码：

#include <windows.h>

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) {
    // 创建窗口
    WNDCLASS wc = {0};
    wc.lpfnWndProc = WndProc;
    wc.hInstance = hInstance;
    wc.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1);
    wc.lpszClassName = "MyWindowClass";
    RegisterClass(&wc);

    HWND hwnd = CreateWindow("MyWindowClass", "My Window", WS_OVERLAPPEDWINDOW,
                             CW_USEDEFAULT, CW_USEDEFAULT, 640, 480, NULL, NULL, hInstance, NULL);

    // 加载图片
    HBITMAP hBitmap = (HBITMAP) LoadImage(NULL, "path/to/image.jpg", IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE);

    // 显示图片
    HDC hdc = GetDC(hwnd);
    HDC hdcMem = CreateCompatibleDC(hdc);
    SelectObject(hdcMem, hBitmap);
    BITMAP bm;
    GetObject(hBitmap, sizeof(bm), &bm);
    StretchBlt(hdc, 0, 0, 640, 480, hdcMem, 0, 0, bm.bmWidth, bm.bmHeight, SRCCOPY);
    DeleteDC(hdcMem);
    ReleaseDC(hwnd, hdc);

    ShowWindow(hwnd, nCmdShow);
    UpdateWindow(hwnd);

    // 消息循环
    MSG msg = {0};
    while (GetMessage(&msg, NULL, 0, 0)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return msg.wParam;
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam) {
    switch (msg) {
        case WM_DESTROY:
            PostQuitMessage(0);
            break;
        default:
            return DefWindowProc(hwnd, msg, wParam, lParam);
    }
    return 0;
}

这段代码使用 Windows 函数加载图片，并使用 StretchBlt 函数将图片绘制在窗口上。你只需要将代码中的 "path/to/image.jpg" 替换为你实际的图片路径即可。
