title: Grey(disabled) text in Visual C++ 2010 Express code. What does it mean? How do I resolve it?
body: <p>Some portion of the C code gets greyed in the IDE. I'm unable to figure out why. This happened in many other sections of the code as well. Some of errors I'm getting show that this code isn't getting recognized by the compiler. Could anyone help me by suggesting what is the cause for greying and also how to resolve it?
  I've attached a snapshot the IDE text editor window. Hope it helps!</p>
