东芝笔试题目
笔试题目(一)
1. 将程序改成Unicode编程需要做哪些修改?
window 2k以后的系统底层都是基于Unicode的,就算你调用ANSI的API(以A结尾比如SetWidowsTextA),系统也会在你的进程默认堆上动态分配一块内存,存放转换后的Unicode字符串,然后把转换后的字符串传递给API,如果调用了返回值为ANSI字符串的API,Windows会在后台进行相反的转换。
其实VC中进行Unicode编程也不麻烦,大概如下:
1.为工程添加UNICODE和_UNICODE预处理选项,在VC.net中就是 项目 -> 属性 -> c/c++ -> 预处理器 在"预处理定义"中加入这两个宏定义(vc6中 project -> settings -> c/c++ -> general 中的 Preprocessor definitions).
2.Include
3.把所有的字符串常量用_T()宏包起来,比如 TCHAR* szText = _T("我的Text");
4.所有的C库字符串操作函数也做相应的替换,比如
strlen ->_tcslen
strcat ->_tcscat
strcmp ->_tcscmp
......
注意,这些函数中的"文本长度"均为字符个数,而非char个数具体参看MSDN.
5.API调用一般不用做特殊处理,当定义了UNICODE和_UNICODE后,所有的API都会被宏指向W结尾的版本(不定义则指向A结尾的`版本).
其实,上面所说的并非强制你使用UNICODE,如果你还想回去使用ANSI,没有问题,把第一步定义的两个宏拿掉就OK了,继续我们的ANSI编程。
2. TCHAR同char的区别
TCHAR 就是当你的字符设置为什么就是什么
例如:程序编译为 ANSI, TCHAR 就是相当于 CHAR
当程序编译为 UNICODE, TCHAR 就相当于 WCHAR ,每个字符占两个字节
3. BOOL同bool的区别
意义上没什么区别,但却是两种类型.
bool应该是C语言里定义的,返回值为true和false(事实上就上1和0)
而BOOL应该是MFC及SDK里定义返回值的.
它的定义应该是:typedef int BOOL;(WINDEF.H中定义)
也就是说它是int型的
返回值是大写的TRUE 和FALSE
定义如下:
#define FALSE 0
#define TRUE 1
(AFX.H中如此定义)
一个是布尔型,一个是整型.
事实上整型如果取1和0就可以代替布尔型了.
