title: Running my program says "bash: ./program Permission denied"
body: <p>I am running Ubuntu on computer 1 and computer 2. I compiled a C++ program on computer 1, and I can execute it from the terminal using <code>./program_name</code>. It runs fine.</p>
  
  <p>However, when I try to do this on computer 2, it says: <code>bash: ./program_name: permission denied</code></p>
  
  <p>What's wrong and what can I do about it?</p>
