          筆試題目(一)

        東芝筆試題目

          1. 將程序改成Unicode編程需要做哪些修改?

          window 2k以后的系統(tǒng)底層都是基于Unicode的,就算你調(diào)用ANSI的API(以A結(jié)尾比如SetWidowsTextA),系統(tǒng)也會(huì)在你的進(jìn)程默認(rèn)堆上動(dòng)態(tài)分配一塊內(nèi)存,存放轉(zhuǎn)換后的Unicode字符串,然后把轉(zhuǎn)換后的字符串傳遞給API,如果調(diào)用了返回值為ANSI字符串的API,Windows會(huì)在后臺(tái)進(jìn)行相反的轉(zhuǎn)換。

          其實(shí)VC中進(jìn)行Unicode編程也不麻煩,大概如下:

          1.為工程添加UNICODE和_UNICODE預(yù)處理選項(xiàng),在VC.net中就是 項(xiàng)目 -> 屬性 -> c/c++ -> 預(yù)處理器 在"預(yù)處理定義"中加入這兩個(gè)宏定義(vc6中 project -> settings -> c/c++ -> general 中的 Preprocessor definitions).

          2.Include (一般在stdafx.h中)然后把所有使用char*定義變量的地方換為L(zhǎng)PTSTR/TCHAR*或LPCTSTR/const TCHAR*(對(duì)應(yīng)于const char*).

          3.把所有的字符串常量用_T()宏包起來,比如 TCHAR* szText = _T("我的Text");

          4.所有的C庫(kù)字符串操作函數(shù)也做相應(yīng)的替換,比如

          strlen ->_tcslen

          strcat ->_tcscat

          strcmp ->_tcscmp

          ......

          注意,這些函數(shù)中的"文本長(zhǎng)度"均為字符個(gè)數(shù),而非char個(gè)數(shù)具體參看MSDN.

          5.API調(diào)用一般不用做特殊處理,當(dāng)定義了UNICODE和_UNICODE后,所有的API都會(huì)被宏指向W結(jié)尾的版本(不定義則指向A結(jié)尾的`版本).

          其實(shí),上面所說的并非強(qiáng)制你使用UNICODE,如果你還想回去使用ANSI,沒有問題,把第一步定義的兩個(gè)宏拿掉就OK了,繼續(xù)我們的ANSI編程。

          2. TCHAR同char的區(qū)別

          TCHAR 就是當(dāng)你的字符設(shè)置為什么就是什么

          例如:程序編譯為 ANSI, TCHAR 就是相當(dāng)于 CHAR

          當(dāng)程序編譯為 UNICODE, TCHAR 就相當(dāng)于 WCHAR ,每個(gè)字符占兩個(gè)字節(jié)

          3. BOOL同bool的區(qū)別

          意義上沒什么區(qū)別,但卻是兩種類型.

          bool應(yīng)該是C語(yǔ)言里定義的,返回值為true和false(事實(shí)上就上1和0)

          而BOOL應(yīng)該是MFC及SDK里定義返回值的.

          它的定義應(yīng)該是:typedef int BOOL;(WINDEF.H中定義)

          也就是說它是int型的

          返回值是大寫的TRUE 和FALSE

          定義如下:

          #define FALSE 0

          #define TRUE 1

          (AFX.H中如此定義)

          一個(gè)是布爾型,一個(gè)是整型.

          事實(shí)上整型如果取1和0就可以代替布爾型了.
