Not "well-defined" is the proper terminology.

• haberman 13y ago
  What is the difference? I do not see "well-defined" in the "Terms, definitions, and symbols" part of the standard.
  • randyrand 13y ago
    It is 'de facto' defined. http://en.wikipedia.org/wiki/De_facto http://en.wikipedia.org/wiki/De_facto :)

      "de facto" defined means nothing. Compilers change and break programs that depend on undefined behavior all the time.

  No. You might be right if we were talking about "proper use" in English as a spoken language, but "undefined behavior" is a technical term defined by the C and C++ ISO standards.

    I see, okay did not know "undefined behavior" was part of ISO. It's pretty unfortunate that I have to pay $30 to see the ISO standard... http://isocpp.org/std/the-standard http://isocpp.org/std/the-standard
