C++技巧之六

 

 void main(void){                    int i = 10;                    printf("i: %d\n", i);                    {                    int i = 100;            /* This statement is fine since it is akin to defining                                                                       a local function within the function. */

/* 此语句很精炼，
因为它在函数中定义了一局部函数的同族。*/                    printf("i: %d\n", i);                    }                    printf("i: %d\n", i);} 
代码清单 6 CRecentFileListEx()函数
class CRecentFileListEx : public CRecentFileList{public:    CRecentFileListEx(UINT nStart, LPCTSTR lpszSection,        LPCTSTR lpszEntryFormat, int nSize,        int nMaxDispLen = AFX_ABBREV_FILENAME_LEN):          CRecentFileList(nStart, lpszSection, lpszEntryFormat, nSize, nMaxDispLen)    {    }                                             BOOL GetDisplayName(CString& strName, int nIndex,        LPCTSTR lpszCurDir, int nCurDir, BOOL bAtLeastName = TRUE) const;}; BOOL CRecentFileListDlgApp::InitInstance(){    ...                    LoadStdProfileSettings();  // Load standard INI file options (including MRU)
// 载入标准INI文件选项(包括MRU)
// Delete the m_pRecentFileList created in the LoadStdProfileSettings.
// 删除在LoadStdProfileSettings中创建的m_pRecentFileList。    delete m_pRecentFileList;     // The nSize argument of the constructor is set to four because the      // LoadStdProfileSettings takes a default of four.  If you specify a      // different value for the nMaxMRU argument you need to change the
// nSize argument for the constructor call.
// 因为LoadStdProfileSettings 取默认值4，所以构造器的nSize参数设置为4。
// 如果你为nMaxMRU参数指定不同的值，你需要为构造器呼叫而改变nSize参数。    m_pRecentFileList = new CRecentFileListEx(0, FileSection, FileEntry, 4);    m_pRecentFileList->ReadList();     ...}
