I posted this just after a question about QBasic and VBasic. I was also wondering, just how do I open files for reading and writing in C++? I really can''t do anything too interesting if my programs can''t use other files and libraries (although I do know how to use include files, but that darn define# statement just pisses me off :-) !) How do I do it? Thanks.

  ifstream fin;		// input streamofstream fout;		// output stream	fin.open("input.txt");	// open inputif(fin.fail()){   cout << "ERROR: Could not find input.txt!\n";   return 1;	}	while (!fin.eof())		// read input file{...}fin.close();

Thanks alot! For some reason I was just having trouble finding out how to do that (I did find one other example, but because it was part of a whole entire program, it was quite confusing!)
