title: Create a Print Function
body: <p>I'm learning Bison and at this time the only thing that I do was the <em>rpcalc</em> example, but now I want to implement a print function(like <code>printf</code> of C), but I don't know how to do this and I'm planning to have a syntax like this <code>print ("Something here");</code>, but I don't know how to build the print function and I don't know how to create that <code>;</code> as a end of line.<br> Thanks for your help.</p>
