title: What's the most efficient way to make bitwise operations in a C array
body: <p>I have a C array like:</p>
  
  <pre><code>char byte_array[10];
  </code></pre>
  
  <p>And another one that acts as a mask:</p>
  
  <pre><code>char byte_mask[10];
  </code></pre>
  
  <p>I would like to do get another array that is the result from the first one plus the second one using a bitwise operation, on each byte.</p>
  
  <p>What's the most efficient way to do this?</p>
  
  <p>thanks for your answers.</p>
