title: Appending to an array in C
body: <p>Let's say I have an array allocated in memory. How do I append directly to the end of the list? By this, I mean directly after the last entry already in the array. </p>
  
  <p>My for loop (i=0;i&lt;100;i++) is only adding elements to an array in certain cases, so it is not possible to append to the array using i.</p>
  
  <p>My main question is: any way to append directly to the end of an array in C?</p>
  
  <p>Thank you</p>
