  • C++ Vector Iterators – Linux Hint

    The main iterators in C++ are Input Iterator, Output Iterator, Forward Iterator, Bidirectional Iterator, and Random Access Iterator. Reverse Iterator is not really an iterator; it is an iterator adaptor. There are some variants to iterators, like a constant iterator.

    An iterator is an elaborated pointer. Like a pointer, it points to objects of the same type in memory at different times. All iterators are dereferenceable, except for the output iterator that is dereferenceable only for a set of types. Dereferenceable means the value pointed to by the pointer or iterator can be obtained using the indirection operator, *. An integer can be added to some iterators in the same way, and for the same purpose, the integer would be added to a pointer.

    The questions for this article are: What are these iterators? Which of these iterators are used with the C++ vector? How are these iterators used with the C++ vector? This article answers all these questions in a simplified way. At the end of this article, when all these questions would have been answered, C++ vector iterators will be intuitive and natural (for the reader).

  • Security breaches where working from home is involved are costlier, claims IBM report

    Firms looking to save money by shifting to more flexible ways of working will need to think carefully about IT security and the additional cost of breaches linked to staff working from home.

    That's according to the latest annual "Cost of a Data Breach Report" conducted by Ponemon Institute along with IBM Security, which found that the average total cost of a remote-working data breach was more than $1m higher than cyberattacks where remote working wasn't a factor.

  • Linux 101: What does "sourcing a file" mean in Linux? - TechRepublic

    Sourcing a file in Linux is a very important concept, but it might not be one you'll use early on in your Linux career. Even so, I'm going to try to explain this challenging concept in a way you can understand it. Sourcing a file makes it possible for an executable to "source" information from a script as though the script had printed its output to the terminal. It's not an easy concept to grasp, so I'm going to show you by way of an example.

  • 3 Ways to install Slack in Ubuntu 20.04 LTS (Focal Fossa) - Linux Shout

  • How to Check Which Desktop Environment You’re Using on Linux

    As you might know, Linux-based operating systems are heavily focused on the command line for performing operations. A minimal distro like Arch Linux will present you with a dark terminal post-installation. What makes Linux distros interactive and user-friendly often goes unnoticed—the desktop environment. Most beginner Linux users are unaware of desktop environments and don't even know which one they're using. Here's how you can check which desktop environment is currently installed on your Linux system.
