title: How does one represent the empty char?
body: <p>I'm currently writing a little program but I keep getting this error when compiling</p>
  
  <blockquote>
    <p>error: empty character constant</p>

  <p>I realize it's because I'm trying to replace a valid char with empty space <code>c[i]=''</code> but I have not been able to find another way to represent it.</p>
