  • How default assignment operator works in struct?

    - by skydoor
    Suppose I have a structure in C++ containing a name and a number, e.g. struct person { char name[20]; int ssn; }; Suppose I declare two person variables: person a; person b; where a.name = "George", a.ssn = 1, and b.name = "Fred" and b.ssn = 2. Suppose later in the code a = b; printf("%s %d\n",a.name, a.ssn);

  • Problem compiling c++ in CodeGear

    - by Carlos
    I have written a C++ program for a University assignment. I used Netbeans 6.8 running on my Mac and the code runs smoothly, no warnings, errors or problems/bugs. However when compiling and running on a Windows computer using CodeGear RAD Studio 2009 (C++ Builder) am getting several errors. [BCC32 Error] main.cpp(51): E2094 'operator<<' not implemented in type 'ostream' for arguments of type 'string' [BCC32 Error] main.cpp(62): E2093 'operator==' not implemented in type 'string' for arguments of the same type [BCC32 Error] main.cpp(67): E2093 'operator==' not implemented in type 'string' for arguments of the same type [BCC32 Error] main.cpp(112): E2093 'operator==' not implemented in type 'string' for arguments of the same type [BCC32 Error] main.cpp(121): E2094 'operator<<' not implemented in type 'ostream' for arguments of type 'string' [BCC32 Error] main.cpp(130): E2093 'operator==' not implemented in type 'string' for arguments of the same type [BCC32 Error] main.cpp(133): E2094 'operator<<' not implemented in type 'ostream' for arguments of type 'string' [BCC32 Error] main.cpp(139): E2094 'operator<<' not implemented in type 'ostream' for arguments of type 'string' [BCC32 Error] main.cpp(153): E2094 'operator<<' not implemented in type 'fstream' for arguments of type 'string' [BCC32 Error] main.cpp(199): E2094 'operator>>' not implemented in type 'fstream' for arguments of type 'string' [BCC32 Error] main.cpp(219): E2094 'operator>>' not implemented in type 'istream' for arguments of type 'string' [BCC32 Error] main.cpp(231): E2094 'operator>>' not implemented in type 'istream' for arguments of type 'string' [BCC32 Error] main.cpp(240): E2094 'operator>>' not implemented in type 'istream' for arguments of type 'string' [BCC32 Error] main.cpp(262): E2094 'operator>>' not implemented in type 'istream' for arguments of type 'string' [BCC32 Error] main.cpp(264): E2094 'operator>>' not implemented in type 'istream' for arguments of type 'string' These are the header files am using #include <iostream> #include <fstream> #include <cmath> #include <stdio> #include <windows> //I added this one just to check and still does not work (I didnt have it on Netbeans/Mac) using namespace std; Any ideas what is producing the errors and how can I fix it?

  • No sound after installing a new Graphics Card

    - by Dan
    I've just upgraded my graphics card to an Asus Geforce 210 and now my system has no sound. I've ran Update Manager and the Additional Drivers utility which installed the latest Nvida driver. The graphics card is connected to my TV via a DVI-to-HDMI (DVI at the PC end) cable for the visual connection, and an audio jack from my onboard soundcard for my audio connection. Any ideas on how to resolve this? I ran this command ubuntu-bug audio And it outputted this: You seem to have configured PulseAudio to use the "pci-0000_05_00.1" card, while you want output from "NFORCE - NVidia CK804". I've tired a bit of messing about with the audio settings but can't get anything to work.

  • Designing a completely new database/gui solution for my compnay

    - by user1277304
    I'm no expert when it come to everything Visual Studio 2010 and utilizing SQL server 2008. I'm sure some of my personal projects I've built for personal use would get laughed off the face of the planet, but SQLCe has been the solution I was looking for those home type of projects. And they work, flawlessly. Now I feel it's time to step up to the big league. I want to develop a complete, unified and module based solution for my company that I'm working for. We're still using stuff from the 80s for goodness sake! I use Excel and query the ancient database on my own because I can't stand the GUI. Nothing against people of age, but the IDE our programmers are using is from the stone age, and they use APL of all things with it. I've yet to see a radio button control anywhere in the GUI where it would make sense. Anyway, I want to do this right from the ground up. I'm by no means a newbie when it comes to programming in .NET 2010, however, I want the entire solution to be professionally done. I want version control, test projects, project flow, SQL 2008 integration and all the bells and whistles that come with that. I know for a fact that if we had something like that running, not only would development costs and time be slashed four fold, but the possibilities for expansion and performance would sky rocket. (Between the GUI an our DB engine, it can only use ONE CORE! ONE! It's 2012 for goodness sake!) Our business is growing and our current ancient solution just can't keep up, and I'd hate to see our business go down in flames because our programmer is stuck in the 80's and refuses to use anything current. So I ask you guys, the experts and know-it-alls, where do I start? Are there any gems of good books out there in the haystack of all "This for dummies" type of deals? I already have several people backing me in this endeavor, and while it may seem brash to just usurp the current programmers, I'm doing this for the company as a whole.

  • New Oracle Solaris 11 Administration book

    - by glynn
    During the development of Oracle Solaris 11, one of the main goals was to modernize the operating system and remove some of the existing frustrations that our administrative audience had in deploying and using the platform within data centers around the world. That meant a comprehensive clean out of some existing technologies to provision the operating system (replacing Jumpstart with Automated Installer) and manage system software (replacing SVR4 with IPS packaging), consolidate the vast spectrum of networking configuration, and enhance the user environment to provide familiarity for those who were used to administering Linux environments among many other things. While some considered the changes to Oracle Solaris 11 as a negative change, most will be impressed at how far we've come - the deeper integration of key technologies, presented in a consolidated and consistent form. It is easier to administer the Oracle Solaris platform that ever before, and I have no doubt that administrators coming from other platforms will be hugely impressed with what they see, especially if they're judging based on past experiences of Solaris 8 and Solaris 9. In fact I'd go further to say that Oracle Solaris 11 is a more powerful, integrated and usable platform that most Linux platforms I've seen. But as with anything, there's always an initial learning curve to get through. We've provided a significant selection of learning materials out on the Oracle Solaris 11 pages on Oracle Technology Network and some great training and certification options. One more option is now available in the form of a book, the Oracle Solaris 11 System Administration The Complete Reference. This provides an exceptional reference to help administrators learn about Oracle Solaris 11, especially those who have come from the Linux platform. As is quoted in the first chapter of the guide: Linux users and developers will find in Oracle Solaris 11 a familiar and quickly productive working environment; we point out similarities and differences between the Linux and Solaris kernels and system administration tools, and describe how typical open source Web development tasks are accomplished in this OS. So I would encourage you to take a read of it and start seriously considering Oracle Solaris 11 to be a platform choice for your data center. Oracle Solaris 11 System Administration The Complete Reference - yours for only $32.50 (if you successfully use the promotion code - otherwise worth shopping around to pick up a good deal).

  • New Java EE/GlassFish Testimonial

    - by reza_rahman
    As you may be aware, we have been making a concerted effort to ask successful Java EE/GlassFish adopters to come forward with their stories. A number of such stories were shared at this year's GlassFish Community event at JavaOne. In addition to Adam Bien's testimonial (which we posted earlier), another story that really stands out is the one from Stephan Janssen. Stephan is one of the main organizers of Devoxx and the webmaster of the popular Parleys e-learning platform. Parleys, which won the Duke's Choice award this year, runs on GlassFish as does the Devoxx CFP/registration website. Stephan's story is particularly interesting because he talks about his reasons and experience of moving from Tomcat to GlassFish and from Spring to Java EE. See what Stephan had to say here.

  • New Book: Oracle Exalogic Elastic Cloud Handbook

    - by user12608550
    Oracle Exalogic Elastic Cloud Handbook, by Tom Plunkett, TJ Palazzolo, and Tejas Joshi, Oracle Press. The well-known characteristics and tiers of cloud computing have spawned myriad implementations by a host of vendors and system integrators. One of these, Oracle's Exalogic Elastic Cloud, part of Oracle's family of Engineered Systems, is a key component of Oracle's public and private cloud computing solutions, providing critical PaaS (Platform as a Service) features for cloud developers. These developers need guidance to take advantage of Exalogic's extensive capabilities, and the Oracle Exalogic Elastic Cloud Handbook, written by three highly experienced Oracle technologists, provides that guidance. Part One of the book covers Exalogic's hardware and software components, and includes a very useful chapter on deployment examples, describing best practices for scalabiity, availability, backup and recovery, and multi-tenant security, including integration with other Oracle Engineered Systems and products such as Exadata and storage subsystems. Part Two is a thorough guide to Exalogic installation features, configuration and monitoring, packaged application software management, and scalable application development. The book also provides an extensive list of online resources, including pointers to Web sites, whitepapers, instructional videos, and other Oracle documentation. So, if you're planning to implement Exalogic as part of your cloud infrastructure, or are considering such, you'll find lots of sage advice and best practices in this handbook.
