C++: Using ifstream with getline();

Check this program

ifstream filein("Hey.txt");
filein.getline(line,99);
cout<<line<<endl;
filein.getline(line,99);
cout<<line<<endl;
filein.close();

The file Hey.txt has alot of characters in it. Well over a 1000

But my question is Why in the second time i try to print line. It doesnt get print?

Solution

  • According to the C++ reference (here) getline sets the ios::fail when count-1 characters have been extracted. You would have to call filein.clear(); in between the getline() calls.
