title: Read a file in by columns in C++
body: <p>I have a file that contains numbers:</p>
  <pre><code>23 899 234 12
  12 366 100 14
  10 256 500 23
  14 888 564 30
  </code></pre>
  <p>How can I read this file by column using C++? I searched YouTube but they only read file by row. If I have to find the highest value from the first column, I need to read it by columns right?</p>
