title: Is 0 an octal or a decimal in C?
body: <p>I have read <a href="https://stackoverflow.com/questions/6895522/is-0-a-decimal-literal-or-an-octal-literal">this</a>. It's octal in C++ and decimal in Java. But no description about C?</p>
  
  <p>Is it going to make any difference if 0 is octal or decimal? This is the question asked by my interviewer. I said no and I explained that it is always 0 regardless whether it is octal or decimal.</p>
  
  <p>Then he asked why is it considered as octal in C++ and decimal in Java. I said it's the standard. Please let me know what is it in C? Will it make any difference? Why are they different in different standards?</p>
