怎么使用dev-c++ ?

小弟我刚学c++,下载了个dev-c++编译器。建立一个工程,main.cpp页面中那么多东西,怎么写程序呢?? 在哪儿写?
  • main.cpp页面:

    #include <windows.h>


    /* Declare Windows procedure */
    LRESULT CALLBACK WindowProcedure
  • (HWND, UINT, WPARAM, LPARAM);

    /* Make the class name into a global variable */
    char szClassName[ ] = "WindowsApp";


    int WINAPI
    WinMain (HINSTANCE hThisInstance,
    HINSTANCE hPrevInstance,
    LPSTR lpszArgument,
    int nFunsterStil)

    {
    HWND hwnd; /* This is the handle for our window */
    MSG messages; /* Here messages to the application are saved */
    WNDCLASSEX wincl; /* Data structure for the windowclass */

    /* The Window structure */
    wincl.hInstance = hThisInstance;
    wincl.lpszClassName = szClassName;
    wincl.lpfnWndProc = WindowProcedure; /* This function is called by windows */
    wincl.style = CS_DBLCLKS; /* Catch double-clicks */
    wincl.cbSize = sizeof (WNDCLASSEX);

    /* Use default icon and mouse-pointer */
    wincl.hIcon = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hIconSm = LoadIcon (NULL, IDI_APPLICATION);
    wincl.hCursor = LoadCursor (NULL, IDC_ARROW);
    wincl.lpszMenuName = NULL; /* No menu */
    wincl.cbClsExtra = 0; /* No extra bytes after the window class */
    wincl.cbWndExtra = 0; /* structure or the window instance */
    /* Use Windows's default color as the background of the window */
    wincl.hbrBackground = (HBRUSH) COLOR_BACKGROUND;

    /* Register the window class, and if it fails quit the program */
    if (!RegisterClassEx (&wincl))
    return 0;

    /* The class is registered, let's create the program*/
    hwnd = CreateWindowEx (
    0, /* Extended possibilites for variation */
    szClassName, /* Classname */
    "Windows App", /* Title Text */
    WS_OVERLAPPEDWINDOW, /* default window */
    CW_USEDEFAULT, /* Windows decides the position */
    CW_USEDEFAULT, /* where the window ends up on the screen */
    544, /* The programs width */
    375, /* and height in pixels */
    HWND_DESKTOP, /* The window is a child-window to desktop */
    NULL, /* No menu */
    hThisInstance, /* Program Instance handler */
    NULL /* No Window Creation data */
    );

    /* Make the window visible on the screen */
    ShowWindow (hwnd, nFunsterStil);

    /* Run the message loop. It will run until GetMessage() returns 0 */
    while (GetMessage (&messages, NULL, 0, 0))
    {
    /* Translate virtual-key messages into character messages */
    TranslateMessage(&messages);
    /* Send message to WindowProcedure */
    DispatchMessage(&messages);
    }

    /* The program return-value is 0 - The value that PostQuitMessage() gave */
    return messages.wParam;
    }


    /* This function is called by the Windows function DispatchMessage() */

    LRESULT CALLBACK
    WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
    {
    switch (message) /* handle the messages */
    {
    case WM_DESTROY:
    PostQuitMessage (0); /* send a WM_QUIT to the message queue */
    break;
    default: /* for messages that we don't deal with */
    return DefWindowProc (hwnd, message, wParam, lParam);
    }

    return 0;
    }

你选择了windows应用程序PROJECT,
windows应用程序是和C++同等地位的编程领域
初学C++往往不在windows环境下编程
(否则,有太多的与C++无关的细节需要学习,很累的)

建议你把工程的属性改为console
也就是和dos类似文本界面
