title: Function prototype in header files
body: <p>I wanted to know what the difference between the following two declarations is in header files
  I have come across both these styles</p>
  
  <pre><code>void some_method(int);
  </code></pre>
  
  <p>and the second style is :</p>
  
  <pre><code>void some_method(int a);
  </code></pre>
  
  <p>Does one style have any benefit over the other. To me one style just does not have the name of a variable and the name of the variable has to be implemented in the accompanying cpp file.</p>
