大家帮我看看这段小代码

[y1018799688]

#include<string>
#include<iostream>
#include<algorithm>
#include<vector>
#include<iterator>
#include<fstream>
using namespace std;

int main()
{
istream_iterator<int> cin_it(cin);
istream_iterator<int> end_of_stream;
vector<int> vec(cin_it,end_of_stream);
sort(vec.begin(),vec.end());
ostream_iterator<int> output(cout," ");
unique_copy(vec.begin(),vec.end(),output);
}

编译时出现这个错误--------------------Configuration: a - Win32 Debug--------------------
Compiling...
a.cpp
E:\C\a.cpp(13) : error C2664: '__thiscall std::vector<int,class std::allocator<int> >::std::vector<int,class std::allocator<int> >(unsigned int,const int &,const class std::allocator<int> &)' : cannot convert parameter 1 from 'class std::istream_ite

大家帮我看看怎么改改

vector<int> vec(cin_it,end_of_stream);
参数类型应该是迭代器 而不是两个对象的范围

[hhh_hao]

istream_iterator<int> cin_it(cin);
istream_iterator<int> end_of_stream;
vector<int> vec(cin_it,end_of_stream)

这段代码没看懂是什么意思

换个编译器吧。

怎么改呢，书上就是这样写的

[無_1024]

嗯楼上正解 换个编译器 VS2010可以运行

[pengzhixi]

vs2008,dev都没任何问题

看来是编译器问题了，谢谢大家咯
