C++ 将 vector 的排序内容写入文件

Question

这当前读取一个 .txt 文件并对内容进行排序。我试图让它将 vector 的那些排序内容写入文件。目前它只写一行，我怎样才能让它把所有行都放在新文件中？太感谢了。 -凯亚

#include <iostream>
#include <string>
#include <vector>
#include <algorithm>
#include <cmath>
#include <fstream>
using namespace std;
inline void keep_window_open() {char ch; cin>>ch;}

int main()
{
    string line;
    ifstream myfile("weblog.txt");
    vector<string> fileLines;

    //stack overflow example
    if (!myfile) //test the file
    {
        cout << "Unable to open the file" << endl;
        return 0;
    }

    while (getline(myfile, line))
    {
        fileLines.push_back(line);
        //cout << line << '\n';
    }

    sort(fileLines.begin(), fileLines.end()); //sorting string vector

    for (string &s : fileLines)
    {
        cout << s << " ";
        ofstream newfile ("newfile.txt");
        newfile << s << " ";
    };

    return 0;
}

Answer 1

ofstream newfile ("newfile.txt");
for (string &s : fileLines)
{
   cout << s << " ";
   newfile << s << " ";
};
