title: The quotation marks " " in flex
body: <p>I am writing a simple scanner in flex. I want my scanner to print out "integer type seen" when it sees the keyword "int". Is there any difference between the following two ways?</p>
  
  <p>1st way:</p>
  
  <pre><code>%%
  int printf("integer type seen");
  %%
  </code></pre>
  
  <p>2nd way:</p>
  
  <pre><code>%%
  "int" printf("integer type seen");
  %%
  </code></pre>
  
  <p>So, is there a difference between writing <code>if</code> or <code>"if"</code>? Also, for example when we see a <code>==</code> operator, we print something. Is there a difference between writing <code>==</code> or <code>"=="</code> in the flex file? </p>
