小编Dom*_*ger的帖子

你能告诉我/*=NULL*/下面的意思吗？

CMyCla::CMyCla(CWnd* pParent /*=NULL*/)
    : CDialog(CCycleTimes::IDD, pParent)
{
    // Some code here
}

顺便说一句,我复制了同一条线.

成功评论为下面的syte

// CMyCla::CMyCla(CWnd* pParent /*=NULL*/)
//  : CDialog(CCycleTimes::IDD, pParent)

否则,评论失败为下面的样式.

/*
    CMyCla::CMyCla(CWnd* pParent /*=NULL*/)
        : CDialog(CCycleTimes::IDD, pParent)
*/

为什么评论操作失败了？
