Is there an easier way to write this code by using like an array to store the names of functions?
for example something like this
Qt Code: 
  1. QString functions [] = { "food()", "calorie" };
  2. for(int i=0;i<2;i++){
  3. output << entrynum->functions[i]
  4. }

I tried doing something like this but doesn't work for me because of the ->

The code I have which works as I wish but doesn't look very neat unfortunately. =/
Qt Code: 
  1. for(int i = 0; i < 9; i++){
  2.         string filename = "/";
  3.         string number;
  4.         stringstream convert;
  5.         convert << i;
  6.         number = convert.str();
  7.          filename.append(number);
  8.          filename.append(".txt");
  9.          string entrynum = "entry";
  10.          entrynum.append(number);
  11.  
  12.         //cout << "The filename is: " << filename << endl;
  13.          QString filename2 = QString::fromStdString(filename);
  14.         QFile i(QDir::homePath() + filename2);
  15.     if (i.open(QIODevice::WriteOnly)) {
  16.         QTextStream output(&i);
  17.         output.setCodec("UTF-8");
  18.  
  19.         for (int i = 0; i < treeWidget->topLevelItemCount(); ++i) {
  20.             ABItem *entrynum =
  21.                     static_cast<ABItem *>(treeWidget->topLevelItem(i));
  22.             if(filename == "/0.txt"){
  23.             output << entrynum->food() << "\r\n" << endl;
