Ah, but it is very important. A pointer identifies a specific location in memory. A handle identifies a resource - which may be relocatable. > another language.

You're the one saying Java has pointers - which means it points to a specific location in memory. So why can't you set that location yourself? > As well as being fractally wrong you are also fractally obtuse. > Deal with it. > /Flibble And you have once again proven you know nothing about what you speak - but you have to continue to make a fool of yourself, anyway.

That's hardly a good enough reason to "correct" me in my use of the word "reference" given that the spec uses the term reference even including "null reference" everywhere else. You're just trolling. The distinction doesn't really matter in Java. > No, you don't understand what they are saying. C++ has both references > and pointers. Java references act like C++ references. Jerry, of course we can compare C++ pointers and C++ references to Java references. Yes, a Java reference (or rather Java's dot operator) implicitly dereferences if you want to access an object's member. But just like C++ pointers Java references can be reassigned and even be null. Anyhow, words mean different things in different contexts. And context matters. I'll stick to Java terminology in the context of Java. I can't believe we're even talking about something as boring and irrelevant as this. So, did any of you guys actually try Rust yet? :) SG |

But it's a well known fact, well known to Mr Flibble, that language specifications always hide their deepest and darkest meanings in the naming of exception classes. > I'll stick to Java terminology in the context of Java. Interesting idea. Weird, almost. > I can't believe we're even talking about something as boring and > irrelevant as this. Just so. |

All you know about Java is you read a couple of pages of a tutorial, and now you think you're an expert.

I point you to eternal life in the paradise of Heaven with God forever in a body like the angels, beautiful, strong, never ages or tires, with unlimited resources to express yourself fully in God's vast universe. Jesus alone makes this possible, so I take time and teach you about Him, asking you to go to Him and prove it all out for yourself. Compare that teaching to your disparaging me and using profanity and see for yourself who's who by our fruit. Thank you, Rick C. Hodgin |

You will die Rick, so do I. There is no Heaven in the sky, Hell does not wait for our dawnfall (LEmmy ). There is no God, no Angels, nothing. Once you realize that, you will spend rest of your life to do something usefull, instead to spew shit all over the place. > Thank you, > Rick C.

If you have issue with my posts, your real root issue is with God, because I teach what He gave us accurately. In that one passage above: (1) Lamb's Book of Life http://biblehub.com/revelation/21-27.htm (2) Lake of Fire http://biblehub.com/revelation/20-14.htm There is no coming back from that. Praying for you, Rick C. Hodgin |

C++ has no idea of the term 'user'. But in Linux systems the command 'su' will do the job. You will need either superuser privilege or the user's password. Marcel |

I cannot understand your question; please explain the problem more clearly. Perhaps it would help to be more concrete. /Jorgen -- // Jorgen Grahn <grahn@ Oo o. . . \X/ snipabacken.se> O o . |

It crashes the program because printMessage is calling printf with a format string that specified %s and %s. However, the variadic arguments passed to printf have type char* and int. Passing an int when printf expects a char* causes undefined behavior. Again, this has nothing to do with implicit conversions. Some compilers match printf arguments against the conversion specifications in the format string. If yours did so, it would have reported that int is incompatible with the second %s. >a member function for every future function that deals with the template >and the matching parameters. (This is the idea behind the scenes, to >have different implementations.) Yes but one of the programmer's responsibilities is to insure that the code generated when an instance of the template function is created is valid for the arguments actually passed. It is possible to call many functions with arguments that are invalid but cannot be detected by the compiler. -- Remove del for email |
