You accept input from the user and do not sanitize it, and then print it out.

Don't do that.

Either do not print the user input at all, or check that the user input is well-formed before you print it, or escape it before printing.

If you think you want to escape the user input, you need to specify what the output target is. Escaping for the console window is different from escaping for a browser.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
