segmentation fault error when parsing string to pointer array with stringstream - c++

Question

I am reading line by line from a text file whose contents are separated by commas and parsed by extracting with getline() into my stringColor, stringName, stringReward variables, passed into my stringstream ss, and then passed to my tileArray pointer array into respective int, string, and int variables.
My program compiles, however when I run it, it generates a Segmentation Fault 11 to what appears to be where I pass the line contents into stringstream. I cannot find where the problem is however...
Perhaps if someone could point out where the error is, I would be greatly appreciative.
This is the format of each line I am trying to read in from the text file.
It should be able to read in any number of lines.
0,tile 1,5
4,tile 2,0
2,tile 4,1

if (inputFile.is_open())
{
while(getline(inputFile, line))
{
++numberOfLines; //value to set tile amount
cout << numberOfLines <<endl;
}
tile *tileArray = new tile[numberOfLines];
string stringColor, stringName, stringReward; //declare these values as strings and later convert
stringstream ss; //stringstream variable to convert string variable
for(int n = 0; n<(numberOfLines-1); n++)
{
getline(inputFile, stringColor, ','); //delimiter at first comma
cout << stringColor << endl;
getline(inputFile, stringName, ','); // delimiter at second
cout << stringName << endl;
getline(inputFile, stringReward); // stop at the end of the line
cout << stringReward << endl;
ss<<stringColor;
ss>>tileArray[n]->color;
ss.str("");
ss.clear();
cout << tileArray[n]->color;
ss<<stringName;
ss>>tileArray[n]->name;
ss.str("");
ss.clear();
cout << tileArray[n]->name;
ss<<stringReward;
ss>>tileArray[n]->reward;
ss.str("");
ss.clear();
cout << tileArray[n]->reward;
}
}
return 0;
}

I would simplify the use of the stringstream object. Using the same stringstream object as an input stream and output stream requires a deep understanding of how the internal position is manipulated.
{
// Create a nested block and a local istringstream in the nested scope
istringstream ss(stringColor);
ss >> tileArray[n]->color;
}
cout << tileArray[n]->color;
Similarly,
{
istringstream ss(stringName);
ss >> tileArray[n]->name;
}
cout << tileArray[n]->name;
and
{
istringstream ss(stringReward);
ss >> tileArray[n]->reward;
}
cout << tileArray[n]->reward;
