请问大神这个程序怎么写，主要是不知道 文件名怎么传

 #include<iostream>
#include<vector>
using namespace std;

int main()
{
    vector<double> vec_num;
    vec_num.push_back(1.1);
    vec_num.push_back(1.5);
    vec_num.push_back(1.2);

    vector<double>::reverse_iterator re_it;
    for(re_it = vec_num.rbegin(); re_it != vec_num.rend(); re_it++)
        cout << *re_it << endl;

    system("pause");
}

反向迭代器reverse_iterator，从rbegin(=end)到rend（=begin-1)反向遍历，仍然通过++.

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

void WriteTxt(const char *in_filename, const char *out_filename_1, const char *out_filename_2){
    ifstream ifs(in_filename); 
    ofstream out_file_1(out_filename_1);
    ofstream out_file_2(out_filename_2);
    istream_iterator<string> ibeg(ifs);  
    istream_iterator<string> iend; 
    vector<string> text;
    copy(ibeg, iend, back_inserter(text));

    vector<string> out_text_1;
    vector<string> out_text_2;
    vector<string>::iterator it;
    for(it = text.begin(); it != text.end(); it++)
    {
        if(atoi((*it).c_str()) % 2 == 1)
            out_text_1.push_back(*it + "\n");
        else
            out_text_2.push_back(*it + " ");

    }
    ostream_iterator<string> os_1(out_file_1, " ");
    ostream_iterator<string> os_2(out_file_2, " ");
    copy(out_text_1.begin(), out_text_1.end(), os_1);
    copy(out_text_2.begin(), out_text_2.end(), os_2);
}


int main()
{
    WriteTxt("E:\\data.txt", "E:\\out_1.txt", "E:\\out_2.txt");
    system("pause");
} 

我的E：\data.txt里面有数字
13
22
5
24

这家伙真的太懒了，字都不码一下
