问题描述
我正在使用mikroC来编写C语言中的一些微控制器代码。但是我b / b
遇到了bool类型不支持的潜在问题
来自编译器投诉的
我如何声明类型bool变量。来自
我从mikroBasic中抽出的论坛帖子，我意识到
bool类型并不完全支持。在mikroC中进行编程时，我得到了一个无效表达式的错误消息。当我宣布
bool类型变量时，说明符需要当我在函数参数中声明bool类型
变量时，以及当我将bool
类型变量声明为文件范围时。我不确定这个邮件列表上是否有任何mikroC
用户，但非常感谢任何评论或
建议。谢谢。
I am using mikroC to program some microcontroller code in C. However I
have come across of potential problem of bool type not being supported
from the compiler complaint on how I declared type bool variable. From
a forum thread that I''ve pulled out from mikroBasic, I realized that
bool type isn''t fully supported. When programming in mikroC, I have
been getting an error message of "invalid expression" when I declared
a bool type variable, "specifier needed" when I declared the bool type
variable within a function parameter and also when I declared the bool
type variable as a file scope. I''m not sure if there are any mikroC
users on this mailing list, but would much appreciate any comments or
suggestions. Thanks.
推荐答案
#include< stdbool.h>
#include <stdbool.h>
我对mikroC（或microBasic）一无所知但我*知道
布尔类型（拼写为_Bool）只是添加了1999年标准中的C语言
大多数编译器都没有完全实现（并且一个重要的
数字根本没有实现它）。此外，它仅拼写为bool。如果
你已经包含了stdbool.h
在C中你可以使用任何整数类型进行布尔工作只要你
理解0如果为false且* any *非零值为真，那么不要
定义一个名为true的常量或TRUE或TRUE并对它进行比较。

I know nothing of mikroC (or microBasic) but I *do* know that the
boolean type (spelled _Bool) was only added to C in the 1999 standard
which is not implemented fully by most compilers (and a significant
number do not implement it at all). Further, it is only spelt "bool" if
you have included stdbool.h
In C you can use any integral type for boolean work as long as you
understand that 0 if false and *any* non-zero value is true, so don''t
define a constant named "true" or "TRUE" and do comparisons against it.

如果你想在你的系统上尝试编译现有代码并且没有bool
，请尝试输入它。
typedef短布尔
#define true 1
#define false 0
