C++ 建造dame期间的CTYPE问题

我正在努力建立一个女人。环境详情：

GCC-GCC版本4.4.2（GCC） ANTLR-ANTLR解析器生成器版本2.7.2

当我试图编译以下代码段时：

#include <functional>
#include <iomanip>

struct compare_without_case_char  : public std::binary_function<char, char, bool>
{
        const std::ctype<char>& ct ;

        compare_without_case_char (const std::ctype<char>& c = std::use_facet<std::ctype<char> > (std::locale::classic()))
                        : ct(c) {}

        bool operator() (char x, char y) const
        {
                return (ct.toupper(x) == ct.toupper(y)) ;
        }
} ;

#包括
#包括
结构比较\u不带\u case\u char:public std:：binary\u函数
{
const std:：ctype&ct；
比较没有大小写字符的字符（const std:：ctype&c=std:：use_facet（std:：locale:：classic（））
：ct（c）{}
布尔运算符（）（字符x，字符y）常量
{
返回值（ct.toupper（x）=ct.toupper（y））；
}
} ;

出现以下错误：

真正的问题是什么以及我如何解决它。 当做

这里唯一的问题是编译器无法找到

std:：ctype

。您必须包含包含它的文件：

#include <locale>

#包括

如果您在functional和iomanipThanks.中没有ctype，请尝试

#包括

，以获得您的支持。
