I bought a book yet and I have learned by means internet donwloadble materials. I feel not confortable using multi-dimensional arrays. I simply cannot understand memory allocation principle. I have got some ideas that require this one, but only thoughts and no action I have done. Unfortunately, the Deitel book don't explore this topic well. Vectors? How to use them insted of multi-dimensional arrays? What benefit do they bring to the source code? Could you help me on this topics? thanks, Roberto Dias Back to top Paolo Alexis Falcone Guest Posted: Wed Jun 30, 2004 5:16 am    Post subject: Re: multi-dimensional array dinamic allocation VERSUS <vecto Roberto Dias wrote: Quote: I'm a newbie in C++ programming.

How to use them insted of multi-dimensional arrays? What benefit do they bring to the source code? Could you help me on this topics? thanks, Roberto Dias C and C++ requires the programmer to manually manage memory allocation issues (there's no automated garbage collection mechanism unlike in Java or Python...). Case in point - if you're to use a list of objects that would change its size on runtime you'd need to allocate memory for object creation - then destroy them properly upon termination of the program - else the memory allocated for the said data structure would not be freed. A knowledge of how pointers work would be needed here. Vectors are similar to arrays, except that the size of the container isn't constrained by the declaration. Since it is a standard container class, the properties of a vector can be manipulated by using the container algorithms as defined in the STL. Bjarne Stroustrup's "The C++ Programming Language" discusses much on C++ programming - and is imho a must-have for C++ programmers. -- Paolo Alexis Falcone [email]pfalcone (AT) free (DOT) net.ph[/email] Back to top Display posts from previous: All Posts1 Day7 Days2 Weeks1 Month3 Months6 Months1 Year Oldest FirstNewest First         C++Talk.NET Forum Index -> C++ language (comp.lang.c++) All times are GMT Page 1 of 1   Jump to: Select a forum C/C++----------------C LanguageC Language (Moderated)C++ Language (Moderated)C++ language (comp.lang.c++)C++ language, library and standards Non-English C/C++ Newsgroups----------------C++ (German)C++ (French)  You cannot post new topics in this forum You cannot reply to topics in this forum You cannot edit your posts in this forum You cannot delete your posts in this forum You cannot vote in polls in this forum Powered by phpBB © 2001, 2006 phpBB Group SEO toolkit © 2004-2006 webmedic.
