int main () {
    // Uncomment to createdata.exe file
    // ofstreamofs("data.exe", ios_base::binary | ios_base::out);
 
    // if(ofs.is_open())  {

       getline(ifs, paragraph);
       ifs.close();
    }
 
    cout << paragraph << endl;
 
    // Converts string
    for (int i = 0; i < paragraph.length(); i++) {
        if (!isspace(paragraph[i])) {
           newParagraph.push_back(paragraph[i]);
        } else {
           if (!isspace(paragraph[i - 1])) {
               newParagraph.push_back(' ');
           }

    if (newOfs.is_open())  {
       newOfs << newParagraph;
