# bugprone-throw-keyword-missing

Warns about a potentially missing `throw` keyword. If a temporary object is created, but the object’s type derives from (or is the same as) a class that has ‘EXCEPTION’, ‘Exception’ or ‘exception’ in its name, we can assume that the programmer’s intention was to throw that object.

Example:

    void f(int i) {
      if (i < 0) {
        // Exception is created but is not thrown.
        std::runtime_error("Unexpected argument");
      }
    }
