分享VC类型问题
有的类型有点规律:像
PCWSTR 指向一个以"NULL"结束的Unicode字符串常量的指针
LPCSTR 指向一个以"NULL"结束的WINDOWS字符串常量的指针
LPCTSTR 指向一个以"NULL"结束的Unicode或Windows字符串常量的指针
LPCWCH 指向一个以"NULL"指向一个以"NULL"结束的Unicode字符常量的指针
LPCWSTR 指向一个以"NULL"指向一个以"NULL"结束的Unicode字符串常量的指针
LPCCH 指向一个Windows字符常量的指针;
C代表const是常量,那W是Unicode字符,T是Unicode或Windows字符串,可移植的;那他们的单词是怎么写啊,我想这样理解了就好记了.Unicode字符和WINDOWS字符有什么区别啊?
还有UINT在16为系统是16位的,在32为系统是32位的.那int在Windows上到底是几位啊,double呢

不用记，需要内存分配得时候用sizeof

x位操作系统的int型一般就是x位了

同意二楼的，不用记的，sizeof(类型）

这是C＋＋在中的一段类型描述：
the C++ types of short, int, and long can represent up to three different integer widths. It would be convenient if each type were always some particular width for all systems; for example, if short were always 16 bits, int always 32 bits, and so on. But life is not that simple. The reason is that no one choice is suitable for all computer designs.
//以下这几句话应该为标准吧！
C++ offers a flexible standard with some guaranteed minimum sizes. Here's what you get:
A short integer is at least 16 bits wide.
An int integer is at least as big as short.
A long integer is at least 32 bits wide and at least as big as int.

自己用sizeof试试就知道了。
例 如：
sizeof( double );
例 如：
sizeof( double );
