最近評論

liangquan6：我想下載下傳您的源代碼，可是不成功，您能發給我一份麼？

[email protected]

另外，按照上面的辦法，我建立的程式可以編譯通過，但是調用

m_openGL.RenderGLScene();沒有畫出什麼東西。

另外調用

m_openGL.SetFullScreen(100,100,100);

螢幕也隻……
xhz：請問您那個demo裡的Filter能否看一下，剛學不知道怎麼寫，多謝！

[email protected]
angel：打debug回車後根本無法粘貼

點右鍵都沒反應的

還有,從哪裡開始複制?從e100到最後那個g?
Angel：哎,看了半天也沒看懂

哪位大俠有空的話給我解釋一下啊

好奇心驅使啊呵呵^_^
phlac：我也是這樣

CString,string,char*的綜合比較

(一) 概述

string和CString均是字元串模闆類，string為标準模闆類（STL）定義的字元串類，已經納入C++标準之中；

CString （typedef CStringT<TCHAR, StrTraitMFC<TCHAR>> CString）為Visual C++中最常用的字元串類，繼承自CSimpleStringT類，主要應用在MFC和ATL程式設計中，主要資料類型有char(應用于ANSI)， wchar_t(unicode)，TCHAR(ANSI與unicode均可)；

char*為C程式設計中最常用的字元串指針，一般以’/0’為結束标志；

(二) 構造

string是友善的，可以從幾乎所有的字元串構造而來，包括CString和char*；

CString次之，可以從基本的一些字元串變量構造而來，包括char*等；

char*沒有構造函數，僅可以指派；

舉例：

char* psz = “joise”;

CString cstr( psz );

string str( cstr );

(三) 運算符重載

a) operator=

string是最友善的，幾乎可以直接用所有的字元串指派，包括CString和char*；

CString次之，可以直接用些基本的字元串指派，包括char*等；

char*隻能由指針指派，并且是極危險的操作，建議使用strcpy或者memcpy，而且char*在聲明的時候如未賦初值建議先設為NULL，以避免野指針，令你抓狂；

舉例：

char *psz = NULL;

psz = new char[10]; //當然，以上的直接寫成char *psz = new char[10];也是一樣

memset( psz, 0, 10 );

strcpy( psz, “joise” );

CString cstr;

cstr = psz;

string str;

str = psz;

str = cstr;

delete []psz;

b) operator+

string與CString差不多，可以直接與char*進行加法，但不可以互相使用+運算符，即string str = str + cstr是非法的，須轉換成char*；

char*沒有+運算，隻能使用strcat把兩個指針連在一起；

舉例：

char* psz = “joise”;

CString cstr = psz;

cstr = cstr + psz;

string str = psz;

str = str + str + psz;

strcat( psz, psz );

strcat( psz, cstr );//合法

strcat( psz, str );//非法，由此可見，CString可自動轉換為const char*，而string不行

c) operator +=

string是最強大的，幾乎可以與所有的字元串變量+=，包括CString和char*；

CString次之，可以與基本的一些字元串變量進行+=而來，包括char*等；

char*沒有+=運算符，隻能使用strcat把兩個指針連在一起；

d) operator[]

CString最好，當越界時會抛出斷言異常；

string與char*下标越界結果未定義；

舉例：

char* psz = “joise”;

CString cstr = psz;

cout << cstr[8];

string str = psz;

cout << str[8];

cout << psz[8];

e) operator== 、operator!=、operator> 、operator< 、operator>= 、perator<=

CString與string之間不可以進行比較，但均可以與char*進行比較，并且比較的是值，而不是位址；

cout << ( psz == cstr );

cout << ( psz == str );

cout << ( str == psz );

cout << ( cstr == psz );//以上代碼傳回均為1

(四) 常用算法
