比較TCHAR []和的char []

Question

你如何比較喜歡兩個值：

TCHAR s[100]; 
CHAR d[100]; 

兩個變量有一個值，那麼你如何比較這兩個值？

Answer 1

在嘗試比較之前，我會將這兩個值轉換爲相同的類型。

BOOL UnicodeToAnsi(LPWSTR pszwUniString, LPSTR pszAnsiBuff, DWORD dwAnsiBuffSize){ 
int iRet = 0; 
    iRet = WideCharToMultiByte(
    CP_ACP, 
    0, 
    pszwUniString, 
    -1, 
    pszAnsiBuff, 
    dwAnsiBuffSize, 
    NULL, 
    NULL 
    ); 
return (0 != iRet); 

}

BOOL AnsiToUnicode(LPSTR pszAnsiString, LPWSTR pszwUniBuff, DWORD dwUniBuffSize){ 

int iRet = 0; 
    iRet = MultiByteToWideChar(
    CP_ACP, 
    0, 
    pszAnsiString, 
    -1, 
    pszwUniBuff, 
    dwUniBuffSize 
    ); 

return (0 != iRet); 

}

Answer 2

如何使用lexicographical_compare和功能類似

bool mycomp (TCHAR c1, char c2) 
{ return tolower(c1)<tolower(c2); } 
bool mycomp (char c1, TCHAR c2) 
{ return tolower(c1)<tolower(c2); }
