title: How to empty a char array?
body: <p>Have an array of chars like char members[255]. How can I empty it completely without using a loop?</p>
  
  <pre><code>char members[255];
  </code></pre>
  
  <p>By "empty" I mean that if it had some values stored in it then it should not. For example if I do strcat then old value should not remain</p>
  
  <pre><code>members = "old value";
  
  //empty it efficiently
  strcat(members,"new"); // should return only new and not "old value new"
  </code></pre>
