Get Line

[cpp noob]

I want to read certain lines from a file, let's say the 4th and the 1st lines. First I used getline (which I read from here: http://www.cplusplus.com/forum/beginner/15303/ ) 4 times to read the 4th line. Using getline again will give me the 5th line, not the 1st line. So how do I get the 1st line?

I think you can solve your problem by having look at cin.ignore();

Have a look at this : http://www.cplusplus.com/reference/iostream/istream/ignore/

Two ways:

Close and reopen the file. Then read again.

filein.close();
filein.open("mydata.txt");
if (filein.is_open())
   std::getline(filein, lineOne);

On the first read store into a different variable.

std::getline(filein, lineOne);
for (int i = 0; i < 3; ++i)
   std::getline(filein, lineFour);
