  c语言制作UI界面需要相关的UI库

  如windows操作系统本身就提供了UI的接口

  一个简单的示例代码如下

  #include <windows.h>

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

  int WINAPI WinMain(HINSTANCE hinstance,HINSTANCE hprevinstance,LPSTR line,int cmd)

  {

  static TCHAR AppName[]=TEXT(

  "99

  ");

  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=AppName;

  if(!RegisterClass(&wndclass))

  {

  MessageBox(NULL,TEXT(

  "This program requires Windows NT!

  "),AppName,MB_ICONERROR);

  return 0;

  }

  hwnd=CreateWindow(AppName,TEXT(

  "九九乘法口诀表

  "),

  WS_OVERLAPPEDWINDOW,

  CW_USEDEFAULT,

  CW_USEDEFAULT,

  CW_USEDEFAULT,

  CW_USEDEFAULT,

  NULL,

  NULL,

  hinstance,

  NULL);

  ShowWindow(hwnd,cmd);

  UpdateWindow(hwnd);

  while(GetMessage(&msg,NULL,0,0))

  {

  TranslateMessage(&msg);

  DispatchMessage(&msg);

  }

  return msg.wParam;

  }

  LRESULT CALLBACK WndProc(HWND hwnd,UINT message,WPARAM wparam,LPARAM lparam)

  {

  HDC hdc;

  PAINTSTRUCT ps;

  RECT rect;

  static x,y;

  int i,j;

  int len;

  TCHAR buf[50];

  TEXTMETRIC tm;

  switch(message)

  {

  case WM_CREATE:

  hdc=GetDC(hwnd);

  GetTextMetrics(hdc,&tm);

  x=tm.tmAveCharWidth;

  y=tm.tmHeight+tm.tmExternalLeading;

  ReleaseDC(hwnd,hdc);

  //MessageBox(NULL,TEXT(

  "Create Successed!

  "),TEXT(

  "Successed

  "),MB_OK);

  //PlaySound(TEXT(

  "hello.wav

  "),NULL,SND_FILENAME|SND_ASYNC);

  return 0;

  case WM_PAINT:

  hdc=BeginPaint(hwnd,&ps);

  GetClientRect(hwnd,&rect);

  //DrawText(hdc,TEXT(

  "Hello World!

  "),-1,&rect,DT_SINGLELINE|DT_CENTER|DT_VCENTER);

  //TextOut(hdc,rect.right/2-(strlen(

  "Hello World!

  ")/2)*x,rect.bottom/2-y/2,TEXT(

  "Hello World!

  "),12);

  for(i=1;i!=10;++i)

  {

  for(j=1;j!=i+1;++j)

  {

  len=wsprintf(buf,TEXT(

  "%dx%d=%-4d

  "),j,i,i*j);

  TextOut(hdc,j*len*x,i*y,buf,len);

  }

  }

  EndPaint(hwnd,&ps);

  return 0;

  case WM_DESTROY:

  PostQuitMessage(0);

  return 0;

  }

  return DefWindowProc(hwnd,message,wparam,lparam);

  }

  上面是一个打印windows下拥有窗口界面的九九乘法口诀表的c语言程序代码

  同样的c语言也会有其它的UI库

  比如Gtk，Gtk是可移植的UI库

  可以使用它在Linux、windows包括mac等等操作系统上做ui程序设计

  一个简单的示例代码如下

  #include <gtk/gtk.h>

  int main(int argc,char **argv)

  {

  GtkWidget *win;

  GtkWidget *label;

  int i,j;

  GString *str;

  gtk_init(&argc,&argv);

  win=gtk_window_new(GTK_WINDOW_TOPLEVEL);

  gtk_window_set_position(GTK_WINDOW(win),GTK_WIN_POS_CENTER);

  g_signal_connect(G_OBJECT(win),

  "delete-event
