title: How does sbrk() work in C++?
body: <p>Where can I read about <code>sbrk()</code> in some detail?</p>
  
  <p>How does it exactly work?</p>
  
  <p>In what situations would I want to use <code>sbrk()</code> instead of the cumbersome <code>malloc()</code> and <code>new()</code>?</p>
  
  <p>btw, what is the expansion for <code>sbrk()</code>?</p>
