矢量< BOOL> [英] vector<bool>
问题描述
在有效的STL中,它表示不应该使用vector< bool>但是使用
dequeue< bool>相反。
但是可以出列< bool>有随机访问迭代器?我这样做了吗?
dequeue< bool> myboolarray;
if(myboolarray [3]){
//这样做...
}
如果没有,还有其他解决方案吗?
谢谢。

PS是的。

容器称为deque,而不是dequeue。抛开
拼写错误,这通常是一个很好的建议,除非你可以忍受
vector< bool>'的限制。

是的,但同样,它是deque< bool>,而不是dequeue< bool>。
我这样做了吗?
dequeue< ; BOOL> myboolarray;
if(myboolarray [3]){
//这样做......
}
是的,如果你修复拼写错误。
祝你好运,

< BLOCKQUOTE>谢谢。我尝试了这个,但它失败了这个编译错误:
Matcher.h:11:错误:ISO C ++禁止声明''deque''没有
类型
Matcher.h:11:错误:预期'';''之前''<''令牌
你能否告诉我为什么?
#include< deque>
#include< algorithm>
class Matcher {
受保护:
deque< bool>内容;
};
In effective STL, it said one should not use vector<bool> but use
dequeue<bool> instead.
But can dequeue<bool> has random access iterator? and I do this?
dequeue<bool> myboolarray;
if (myboolarray[3]) {
// do this...
}
if not, is there another solution?
Thank you.

P.S. Yes.

The container is called a "deque", not a "dequeue." Leaving aside the
spelling error, that''s often good advice, unless you can live with
vector<bool>''s limitations.
But can dequeue<bool> has random access iterator?
Yes, but again, it''s a deque<bool>, not dequeue<bool>.
and I do this?
dequeue<bool> myboolarray;
if (myboolarray[3]) {
// do this...
}
Yes, if you fix the spelling error.
Best regards,
Tom
Thanks. I tried this, but it fails with this compiler error:
Matcher.h:11: error: ISO C++ forbids declaration of ''deque'' with no
type
Matcher.h:11: error: expected '';'' before ''<'' token
Can you please tell me why?
#include <deque>
#include <algorithm>
class Matcher {
protected:
deque<bool> content;
};
