title: C++ convert a float array to float* (pointer)
body: <p>I wonder how to convert a float array to a float* 
  I have this situation :</p>
  
  <pre><code>float* floatTab = {12f, 0.5f, 3f};
  </code></pre>
  
  <p>It gives me an error here. but if I write it like this <code>float floatTab[3] = {12f, 0.5f, 3f};</code>it compiles alright. </p>
