    ifstream finp("./src/example.txt");
    ofstream fout("./src/example2.txt");
    if (!finp || !fout)
    {
        std::cout << "Error opening file\n";
        return 1;
    }

    copy(istream_iterator<char>(finp >> noskipws), istream_iterator<char>(), ostream_iterator<char>(cout));
    finp.clear();
    finp.seekg(0);
    finp.setf(ios_base::skipws);
    std::string word;
    std::string m,n;
    cout << endl;
    cout << endl;
    cout << "Ce cuvint doritzi sa modificatzi? : ";

    cout << "Cu ce cuvint doritzi sal modificatzi? : ";
    getline(std::cin, n);
        bool found = false;
        while (!finp.eof() && !(finp >> word).fail())

Im not very good with fstream yet but you dont need to use

std::

aslong as you have

using namespace std;
