title: How to read a certain line from a file and read from that point below, in c++?
body: <p>I have a txt file, with some numbers. Let's say I have these lines.</p>
  
  <p>124</p>
  
  <p>559</p>
  
  <p>774</p>
  
  <p>12</p>
  
  <p>145</p>
  
  <p>698</p>
  
  <p>So there are 6 lines, let's say, I would like to read the file from 12 and below, is there a function in c++ that returns the cursor of the file? I don't know prior what are the values, I was just trying to explain what I would like to do. 
  So for example if I would like to read the values 12, 145, 698, is it possible, and ignoring the prior values, not deleting.</p>
