大家好，想问一个c++关于函数对象的问题。代码如下：
1 #include
2 #include
3 template
4 class display:public std::unary_function{
5 public:
6 display(std::string &ths;):type(ths){}
7 void operator()(typename T::value_type &ths;){
8 std::cout<<<c("this is a string");
18 c(b);
19 return 0;
20 }

结果编译器报错，如下：
display.cpp: In function ‘int main()’:
display.cpp:17: 错误： 对 ‘display, std::allocator > >::display(const char
[17])’ 的调用没有匹配的函数
display.cpp:6: 附注： 备选为： display::display(std::string&) [with T
= std::basic_string, std::allocator >]
display.cpp:4: 附注： display, std::allocator > >::display(const
display,
std::allocator > >&)
display.cpp:18: 错误： 对 ‘(display, std::allocator > >) (std::string&)’ 的调用
没有匹配
display.cpp:7: 附注： 备选为： void display::operator()(typename
T::value_type&) [with T = std::basic_string, std::allocator >]
谁能告诉我那里错了，我头都大了！！！！！

char*不能自动转换成std::strin

那应该怎么办阿？

displayc(string("this is a string"));
学C++不啃本厚书是不行的。

是阿，正在努力。不过我记得一个const char* 的指针是自动转换成字符传的阿。
string有一个构造函数不就是
string(const char *)吗。我照你说的改了一下，好象还不能行阿。要不你在你机
子上试一下吧，看看是不是我机子所装库的问题。谢谢了。

1. #include  这样才有 char * -> string
2. display(std::string &ths;) 最好加const
   display(const std::string &ths;)
3. 如果有1和2，c的构造就不必显示类型转换
4. operator()的参数是string::value_type,即char&, 不是string

Python 邮件列表，你好 

#include
#include
template
class display:public std::unary_function
{
public:
 explicit display(const std::string &ths;):type(ths){}
 void operator()(T &ths;)
 {
  std::cout<<< c("this is a string");
 c(b);
 return 0;
}

你试试这样行不行。

你好，首先要谢谢你，你提出的四条建议，前三条我记下了，对于最后一条我还有 
点小问题。现在我想让display（）能够以string为参数，我应该怎么声明？如果 
把value_type去掉的话，好象还是通不过，恳请指教！

我想用string类型的作参数，那么我应该如何声明？谢谢。

呵呵，因为我认为，学python的大部分都是c++的高手阿。别的地方我又找不到人
指点。只好。。。。。。。
primer上关于函数对象的内容我以前大致看过，不过没有动过手，现在动手的时候
才发现问题多多阿。还是python的好阿，这下谈到python了吧。嘿嘿。

你要的可能是如下代码：

#include 
#include 
#include 

template
class display : public std::unary_function
{
public:
    display(const std::string &ths;) : type(ths) {}
   
    void operator()(const T &ths;)
    {
        std::cout << type << ths << std::endl;
    }
   
private:
    std::string type;
};

using namespace std;

int main()
{
    string b = "what's the wrong?????????";
    display c("this is a string");
    c(b);
    return 0;
}
