array size defined by file.

[MshifterM]

Is there a way to define an arrays size using a file? I have a file with 5 names and scores, I don't want to define a specific number to the array just in case I want to add more names and scores to it.

here is what I got so far.

int num;
string filename;
cin >> filename;
ifstream thename (filename);
vector<string> thenames[num];
vector<double> thescores[num];
  for (int p = 0; p < num; p++){
			inputname >> thenames[i]>>thescores[i];
		}

Don't use an array. Use a std::vector:
http://www.cplusplus.com/reference/vector/vector/
http://en.cppreference.com/w/cpp/container/vector

Even better, use a std::map or a std::multimap depending on whether a player can have multiple scores or not.

Also, loop on the input operation rather than assuming in advance that you know how many scores are in the files.
