在vc中，经常有种数据类型；“bool”----是什么意思？

[kingofvc]

true false
两种状态的布尔型变量
看c＋＋语法

C++ Specific :
This keyword is an integral type. A variable of this type can have values true and false.
The bool type participates in integral promotions. An r-value of type bool can be converted to an r-value of type int, with false becoming zero and true becoming one.

Microsoft Specific:
In Visual C++4.2, the Standard C++ header files contained a typedef that equated bool with int. In Visual C++ 5.0 and later, bool is implemented as a built-in type with a size of 1 byte. That means that for Visual C++ 4.2, a call of sizeof(bool) yields 4, while in Visual C++ 5.0 and later, the same call yields 1. This can cause memory corruption problems .

#define int BOOL
#define int bool
#define 1 TRUE
#define 1 true
#define 0 FALSE
#define 0 false

哈哈~~~~~~~~~~~~~

有意思！

不过
#define int bool
是错的！因为在VC中bool是关键字，新加的数据类型！

[寂寞漂泊]

都说完了

[qiuanhong]

呵~~~~~~~~~~~楼上都说了

慢，好象不对啊！： 111222(www.mozilla.org)
因该是#define BOOL int吧？！

不过其实用的是
typedef int BOOL;

[fhbkyo]

不会吧，还有人问这问题？？？
我眼睛应该没问题的！！
BOOL 的返回值是 TRUE AND FALSE
用来判断某表达式的真假，其他的他们也都说了
