In your original post you asked for standard C++, so that is what I gave you.

string curLine;<br />
f[x] >> curLine;

ifstream * f[3];<br />
	f[0] = new ifstream(string(map + ".ml1").c_str());<br />
	f[1] = new ifstream(string(map + ".ml2").c_str());<br />
	f[2] = new ifstream(string(map + ".ml3").c_str());

string curLine;<br />
			(ifstream&)f[x] >> curLine;
