title: What is the difference between execl and execv?
body: <p>I use <code>execv</code> instead of <code>execl</code>. To use <code>execv</code>, I create an array and put arguments that I use with <code>execl</code> in there. Then I put this array into <code>execv</code> </p>
  
  <p>I know I have to use an array of arguments for <code>execv</code> but why? What is the difference between <code>execl</code> and <code>execv</code>?</p>
