From what it sounds like the data that needs to be placed into the array is of type <string>.

I am assuming the file can change in size so there is no point in using a standard size array. You should use a <vector>, which is a resizable array

[blue]
#include <vector>  [green]//Place this with the rest of the includes [/green]
vector <string> myData; [green]//A vector of strings[/green]

[green]//Do some file reading stuff here
You are probably using fstream?
So reading the file would be like:
[/green]

while(myFile.eof()!)
{
   myStream.getline(SomeCharBuffer,1000);
   [green]//As you are reading data in you can push things on to the back of the vector[/green]

   myData.push_back(SomeCharBuffer);

}

[green]//When you are done you can iterate through the vector just as you could with a standard array [/green]
for (int i =0;i<(int)myData.size();i++) cout << myData[i] << endl;

I hope that helps!

I think this should work.

#include <fstream>
using std::ifstream;

#include <vector>
using std::vector;

#include <string>
using std::string;

int main()
{
   ifstream fileIn( "C:\\myfile.txt" );
   string buf;
   vector<string> myArray;

   while ( fileIn.eof() == false )
   {
      fileIn.get( buf, ',' );
      myArray.push_back( buf );
   }

   fileIn.close();

   // Now do something with the array...
   return 0;
}
