c语言的爱心代码会动的

以下是使用C语言实现动态爱心的代码，它使用了Windows API来创建窗口和绘制图形：

#include <windows.h>
#include <math.h>

#define PI 3.14159265358979323846

LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
                   PSTR szCmdLine, int iCmdShow)
{
    static TCHAR szAppName[] = TEXT("Heart");
    HWND hwnd;
    MSG msg;
    WNDCLASS wndclass;

    wndclass.style = CS_HREDRAW | CS_VREDRAW;
    wndclass.lpfnWndProc = WndProc;
    wndclass.cbClsExtra = 0;
    wndclass.cbWndExtra = 0;
    wndclass.hInstance = hInstance;
    wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
    wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
    wndclass.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
    wndclass.lpszMenuName = NULL;
    wndclass.lpszClassName = szAppName;

    if (!RegisterClass(&wndclass))
    {
        MessageBox(NULL, TEXT("This program requires Windows NT!"),
                   szAppName, MB_ICONERROR);
        return 0;
    }

    hwnd = CreateWindow(szAppName, TEXT("Heart"),
                        WS_OVERLAPPEDWINDOW,
                        CW_USEDEFAULT, CW_USEDEFAULT,
                        400, 400,
                        NULL, NULL, hInstance, NULL);

    ShowWindow(hwnd, iCmdShow);
    UpdateWindow(hwnd);

    while (GetMessage(&msg, NULL, 0, 0))
    {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }

    return msg.wParam;
}

void DrawHeart(HDC hdc, int x, int y, int size)
{
    double angle, radian;
    int px, py;
    int i;

    for (i = 0; i < 360; i++)
    {
        angle = (double)i;
        radian = angle * PI / 180.0;
        px = (int)(16.0 * pow(sin(radian), 3) * size + 0.5);
        py = (int)(-(13.0 * cos(radian) - 5.0 * cos(2 * radian) - 2.0 * cos(3 * radian) - cos(4 * radian)) * size + 0.5);
        SetPixel(hdc, x + px, y + py, RGB(255, 0, 0));
    }
}

LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
    static int cxClient, cyClient;
    HDC hdc;
    PAINTSTRUCT ps;

    switch (message)
    {
    case WM_SIZE:
        cxClient = LOWORD(lParam);
        cyClient = HIWORD(lParam);
        return 0;

    case WM_PAINT:
        hdc = BeginPaint(hwnd, &ps);
        DrawHeart(hdc, cxClient / 2, cyClient / 2, min(cxClient, cyClient) / 30);
        EndPaint(hwnd, &ps);
        return 0;

    case WM_DESTROY:
        PostQuitMessage(0);
        return 0;
    }

    return DefWindowProc(hwnd, message, wParam, lParam);
}

运行后会弹出一个窗口，里面会动态地显示一个红色的爱心。
