title: What does back slash "\" really mean?
body: <p>I'm wondering about Java's backslash. How does the computer or the compiler see this backslash and how is it stored in computer?</p>
  
  <p>I read that backslash removes the special meaning of the following character. But how does a computer treat this one and in what conditions treat it in some other ways?</p>
  
  <p>For example the null character <code>\0</code> in C programming, is the end of the string, but is it a single character or two characters, i.e., backslash + zero? </p>
  
  <p>The objective of back slash is to indicate for humans or to indicate for 0-1 computer?</p>
