C - How to read certain lines from a file? ( Not all lines or entire file but just certain lines)

Question

I tried looking for similar questions that could find an answer to my question but i couldn't seem to find it. Could someone please tell me is there any way to read certain lines from the .txt file. For example i would like to read lines 2,3,5 from the text file.

Example of text file:

1255466889436     //Line 1 - I want to read this line
5489784642165     //Line 2
4984651425165     //Line 3 - I want to read this line
4968164816514     //Line 4
4161654168468     //Line 5 - I want to read this line

It would be nice if somone could show example code cause im really stumped at the moment.

Answer 1

Read all lines, discard the ones you don't need.

You can seek to any offset in a file, but which line is offset 5000? That depends on how many newline characters there were in the previous 5000 characters. And unless you check all characters, you don't know.
