自己调试不来TT

编写的函数放在这个文件里   get.hpp
复制内容到剪贴板
代码:
istream& get(istream& in){
int i;
        while(in>>i,!in.eof()){
                if(in.bad())
                throw runtime_error("IO stream corrupted");
                if(in.fail()){
                cerr<<"bad data,try again";
                        in.clear;
                        in.ignore(200,'');
                        continue;
                }
        cout<<i<<endl;        
}
in.clear();
return in;}
在这个源函数里调用
复制内容到剪贴板
代码:
#include"get.hpp"
#include<iostream>
#include<stdexcept>
using namespace::std;

int main(){
        double j;
                cin>>j;
        get(cin);

        return 0;
}
出现了
