C99中的BOOL数据类型是什么 [英] What is BOOL datatype in C99

问题描述

ANSI C99中的BOOL数据类型是什么？我希望它与BOOLEAN有关。

我搜索了互联网，但最终没有使用的信息。

寻找BOOL的详细说明..... ...........

是否有基于ANSI C99的编译器可从互联网下载？



谢谢.........

解决方案

让我知道你发现了什么。我以为BOOL是一个unsigned int的Microsoft typedef。你是测试它是真还是假，因为它可能包含0或1以外的数字。


FALSE是：


#define FALSE 0


和TRUE是：


#define TRUE！FALSE

"可能的数据类型的完整列表如下：


bool（根据C99）

char

unsigned char

signed char

int

unsigned int

signed int

short int

unsigned short int

签名短int

long int

签名long int

unsigned long int

浮动

双倍

长双倍

我无法找到（可能）该书中的任何其他内容，因为它基于ANSI C89（可能）。

就是这样。我所知道的BOOL目前就是这个。欢迎任何有关此事的帮助.............

~~感谢~~

有BOOL和bool之间的区别。我的意思是，视觉差异。


在C ++中，bool是一个包含true或false的类型：

展开 | 选择 | Wrap | 行号

What is BOOL datatype in ANSI C99? I expect it to be related with BOOLEAN.
I searched internet for it but ended with information of no use.
Looking for an detailed description of BOOL................

Is there any ANSI C99 based compiler for download from internet?


THANKS.........

解决方案

Let me know what you find out. I thought BOOL was a Microsoft typedef of an unsigned int. You were you test it a TRUE or FALSE since it could contain numbers other than 0 or 1.

FALSE is:

#define FALSE 0

and TRUE is:

#define TRUE !FALSE

In this book, on page-205 , it is mentioned that-
__________________________________________________ _______________
"A complete list of possible data types is as:

bool (according to C99)
char
unsigned char
signed char
int
unsigned int
signed int
short int
unsigned short int
signed short int
long int
signed long int
unsigned long int
float
double
long double

I couldnot find (probably) anything else about it in that book as it is based on ANSI C89 (probably).
That''s it. All that I know about BOOL presently is this. Any help in this matter is welcomed.............

~~THANKS~~

There is a difference between BOOL and bool. I mean, a visual difference.

In C++ bool is a type that contains true or false:

Expand|Select|Wrap|Line Numbers
