请问一个问题：关于循环的？谢谢

Question

while()
{
while()
{
}
if(){}
}
能否使外层循环先停止，然后等待一个条件成立后继续循环呢？谢谢

Answer 1

while()
{
if(!)
 continue;
while()
{
}}

Answer 2

POSITION pos=ProgramList.GetHeadPosition();
while(pos!=NULL)
{
    pProgramObject=(CProgramObject *)ProgramList.GetAt(pos);
POSITION pos1=pProgramObject->WndList.GetHeadPosition();
while(pos1!=NULL)
{
if(dwExitCode==STILL_ACTIVE)continue;
    pWndObject=(CWndObject *)pProgramObject->WndList.GetAt(pos1);
// POSITION pos2=pWndObject->PicFileList.GetHeadPosition();
//         while(pos2!=NULL)
// {
//    Parameter *pParameter=new Parameter;
//        pParameter->pWndObject=pWndObject;
//        //pParameter->pPicFileObject=m_Wnd.pPicFileObject;
//    pParameter->pPicFileObject=(CPicFileObject *)pWndObject->PicFileList.GetAt(pos2);
//    pParameter->pWndObject->m_pNewStatic->ShowWindow(SW_SHOW);
pThread=AfxBeginThread(AutoDisplayThreadProc,pWndObject);           
// pWndObject->PicFileList.GetNext(pos2);
// }
// pWndObject=(CWndObject *)pProgramObject->WndList.GetNext(pos1);
//            DWORD dwExitCode; pWndObject=(CWndObject *)pProgramObject->WndList.GetNext(pos1);
            ::GetExitCodeThread(pThread->m_hThread,&dwExitCode);
     
}
// ::GetExitCodeThread(pThread->m_hThread,&dwExitCode);
        pProgramObject=(CProgramObject *)ProgramList.GetNext(pos);
}
看看着改怎么改呀谢谢

Answer 3

POSITION pos=ProgramList.GetHeadPosition();
while(pos!=NULL)
{
    pProgramObject=(CProgramObject *)ProgramList.GetAt(pos);
POSITION pos1=pProgramObject->WndList.GetHeadPosition();
while(pos1!=NULL)
{
if(dwExitCode==STILL_ACTIVE)continue;
    pWndObject=(CWndObject *)pProgramObject->WndList.GetAt(pos1);
pThread=AfxBeginThread(AutoDisplayThreadProc,pWndObject);           
pWndObject=(CWndObject *)pProgramObject->WndList.GetNext(pos1);
            ::GetExitCodeThread(pThread->m_hThread,&dwExitCode);
     
}
        pProgramObject=(CProgramObject *)ProgramList.GetNext(pos);
}
帮忙给看一下怎么改呀
死循环谢谢

Answer 4

为什么不把pos记下来，条件成立后下次循环继续从pos开始循环？

Answer 5

while(pos1!=NULL)
{
      if(dwExitCode==STILL_ACTIVE)continue;
这里当然死循环了，pos1不会变了

Answer 6

你可以使用 goto 语句来完成
