title: C++ Ignore Empty First Line
body: <p>How do I ignore an empty first line in "input.txt"? I don't necessarily know that there is an empty line (in this particular case there is, but I want to make my code generic), so I need to be able to read the line if there is information, or skip it if it is blank. This is just for the first line.</p>
  
  <pre><code>while (getline(mcFile, line)) { 
      istringstream liness2(line); ... }
  </code></pre>
  
  <p>That's how I'm reading the lines. If I knew for certain that any input file I ran this on had an empty first line, I would just do "getline" before, but I don't know that.</p>
