title: No output appears in eclipse
body: <p>I'm writing a code that output an output when using porlandc++ but when using eclipse it doesn't, a "Nothing to build for Help" message appears in the console. my file's name is "Help".
  Even I've tried to debug it putting a breaking point on the first printf function in the code but the debugger always jump to  the end of the code?</p>
  
  <p>I'm new with eclipse so I'll be grateful if you help </p>

  <p>By the way, when I started debugging, many threads appeared not just one, and when trying to stop them, all of them stop except the last one, don't know why?</p>
  
  <p>as I said I'm new with eclipse trying to learn how to use it in debugging instead of the porland c++</p>
  
  <p>thanks a lot</p>
