Welcome to the final tutorial of the series on standard C. This article will cover the linked list abstract data type (ADT). There will be a lot of abstraction to try to deliver the understanding in the most basic way for easiest interpretation of what they are and how they work, then we will get into the guts of it and learn the technical code underneath. For those who have yet to grasp the concept of pointers, it's advisable that you do that first before approaching this. Having learned thi...
Many of our members here at Null Byte are aspiring hackers looking to gain skills and credentials to enter the most-valued profession of the 21st century. Hackers are being hired by IT security firms, antivirus developers, national military and espionage organizations, private detectives, and many other organizations.
To say we're a nation of coffee-lovers is putting it mildly. Americans consume 400 million cups of joe in one day alone, but how well do we actually know our morning BFF? We know it comes from a bean, and that more coffee drinks exist than there are ways to skin a pig, but what else?
Many of my aspiring hackers have written to me asking the same thing. "What skills do I need to be a good hacker?"
While many of the features in the iPhone 16 and 16 Pro series build on what we've seen in previous iPhone models, Apple has packed the 2024 lineup with iOS 18 and plenty of fresh upgrades worth considering.
When typing an email or website address in a compatible input field on an iPhone, most people will manually type in the domain extension. But there's a much faster way to enter domain suffixes for email addresses and website URLs that you should be using on your keyboard. Even better, there's a way to customize what domain extensions appear in the keyboard shortcut!
You probably know of Apple's Text Replacement feature for iOS, iPadOS, and macOS, but you're probably not using it as much as you should. With it, you can create your own keyboard triggers for almost anything you can think of, whether it's an email address or an entire email. There are endless reasons to create custom text replacements — and we'll show you why.
Thousands of emoji are available on iPhone, iPad, and Mac, and you can use these in many of the apps you have installed on your Apple devices. But there's one emoji you'll likely never see on any of Apple's official emoji keyboards, and its absence may surprise you at first, considering it's embedded in virtually every Apple product. That emoji is, of course, the Apple logo icon.
Whenever your iPhone's ringer is on, you'll hear Apple's iconic "Connect Power" chime every time you connect it to a wired or wireless power source, which lets you know that charging has started. There's no way to disable the sound without turning on Silent mode, but there is a way to make Siri automatically say whatever you want after a successful connection.
When Steve Jobs introduced the first iPhone, he pointed out that the biggest problem with physical keyboards on mobile phones is that they're always there, whether you need them or not. Now, 17 years later, a new company is bringing us full circle, giving us the best of both worlds: a physical keyboard for iPhone that can disappear whenever you want.
With iOS 17, Apple News integrates more deeply with Apple Podcasts and Apple Stocks and has become a bit more fun thanks to new crossword puzzles. But that's not all that appears in the updated News app.
A new feature in Apple's latest big iPhone software update lets you personalize how you appear on other people's incoming call screens and even customize individual contacts on your own incoming call screen if they don't have a preferred style to show you.
If you think you know everything there is to know about using emoji on your iPhone, think again. You may be aware of a few of these tricks, but I'm confident there's at least one or two here that you overlooked or never thought possible. Feel free to prove me wrong.
When setting up your home office or giving it a makeover, the desk is the key to making the room a functional workspace. And if you're in there all day, it also has a significant impact on your health. Standing desks can help offset some of the adverse health risks associated with sitting all day, but it's hard to find a decent standing desk that won't break the bank. That's where Flexispot comes in.
Whether you drop your iPhone into a toilet or your dog's water bowl or regularly take it into the shower or pool, water will likely become nestled inside its speaker grilles. Water exposure causes audio playback through the speakers to soften and sound muffled, and getting that water out is no easy task. Luckily, there's an app for that.
The hottest word game right now is Wordle, a simple game that gives you six chances to guess the five-letter word of the day. I've already shown how you can add the real Wordle app — not a fake clone — to your iPhone or Android phone's home screen. But there's also a way to save Wordle for offline gameplay for years to come.
The new Material You theme engine with its fancy widgets is a sexy change for Android, but there's another new Android 12 feature that's more than just pretty colors and curves.
The makers of arguably the two most important mobile AR apps, Niantic and Snap, both had good news this week, with the former preparing to replicate its success with Pokémon GO for another franchise and the latter notching another popular augmented reality Lens for Snapchat.
We're still basking in the afterglow of the HUGE Snap Partner Summit last week, where Snap made Snapchat a much stronger augmented reality platform while also unveiling the AR smartglasses version of Spectacles. This week, we got a peek at how Spectacles AR started and got our hands on Lenses from Lego and Disney featured during the keynote.
Most of you probably hate ads on your smartphone, but they're a part of modern digital life. As long as apps like Instagram are free to use, then we'll need to pay by dealing with posts, videos, and pop-ups trying to sell us stuff. Well, not necessarily, so long as you're OK with a few compromises.
It's getting harder and harder to escape ad tracking by the day. For the latest example, look no further than T-Mobile. The No. 2 carrier updated its privacy policy on Feb. 23, 2021, indicating that it would start sharing customer data with advertisers under the guise of more relevant ads starting April 26. If that's not something you'd like to participate in, there's a way to opt-out.
URL tracking codes: you'll see them on almost every link you copy online to share with friends and followers. It could be tens or hundreds of extra characters appended to the end of a URL, which websites and marketers use to tell how you got to the link in the first place. These excess tracking tokens not only make the links you share look sloppy and spammy — they could even invade your privacy.
Outside of plastic surgery disasters or costumes, augmented reality is the closest we can get to morphing our likenesses into those of animals.
Apple's password manager, iCloud Keychain, lets you securely save important login credentials for apps, websites, and services that sync up across all of your Apple devices — iPhone, iPad, iPod touch, and Mac. One of its biggest highlights is that it can create strong passwords for you. Unfortunately, it doesn't always work, and in those cases, there are other ways to generate random, strong passwords.
ADB and Fastboot are powerful tools that have always required a computer. But with the right setup, you can now send commands to a phone using another phone.
One thing you can expect from Apple is that big features work right out of the box. The company designs its products to be easy to use for any experience level, so you might expect the same to be true for 5G, one of the biggest selling points for the iPhone 12, 12 mini, 12 Pro, and 12 Pro Max. Yet, you might have trouble getting 5G to work on your brand new iPhone. Here's how to avoid that.
Excited about experiencing blazing-fast 5G speeds on your iPhone 12, 12 mini, 12 Pro, or 12 Pro Max? Well, that brand new iPhone you just bought might not actually be using 5G, even when you see that 5G symbol in the top right. Unless you follow these instructions, your iPhone will use regular old 4G LTE more often.
Apple just pushed out iOS 14 to everyone on Sept. 16, but you may not want to jump right into updating your iPhone. If you have Automatic Updates turned on, you may want to turn it off real quick before it tries to download and install iOS 14 before you're ready.
Directing a message at a specific person in a group conversation, or to a select few people in the group, can be difficult if you're in a particularly active or hectic chat. Notifications and badges on your iPhone can help you keep track of important messages, but it's still easy to miss one meant for you and not the entire group — which is why you can now mention contacts, or get tagged, in Messages on iOS 14.
Are you tired of endless rows and columns of apps on your home screen? Before iOS 14, your only option was to hide apps in folders, uninstall them, or use some sort of elaborate workaround. You could hide a few stock apps easily enough, but that's it. Now, in the latest version of iOS, you can hide apps for real, and even hide entire home screen pages, and still access the apps in one convenient drawer.
"What's your Wi-Fi password?" That's usually the first thing guests ask for when you have them over. You tell them the network name, then try to explain your complicated hacker-resistant password, which becomes a whole ordeal. But there's a better way to do it, which doesn't rely on using the same mobile OS as your guests.
If you are reading this article right now on your Galaxy Note 20, you are using one of the most powerful smartphones on the market — but are you taking full advantage of it? The answer is likely no, but you can change this with a few apps.
In a similar vein to Facebook's colorful backgrounds for text posts, Instagram has a way to add vivid text-only status updates for your stories. That way, you can conjure up colorful stories that make a statement without even needing to take a photo or video in the first place. And now there are even more fonts to choose from.
A modern iPhone is capable of running sophisticated, exquisitely-rendered games that rival titles on current-generation consoles. However, there is some value in classic video game titles, whether you grew up playing games on the Atari 2600, Nintendo Entertainment System, and Sega Genesis or not.
Thanks to numerous smartwatch deals this holiday season, many people are receiving their first one. But what exactly can they do? In regards to fitness, quite a lot. With a growing list of sensors and software updates, these small devices can be the very thing you need to ultimately reach your fitness goals.
In a bold move, Samsung has decided to forgo the Galaxy S11 moniker and jump straight to the S20. Perhaps it's marketing for the new 20:9 aspect ratio and 120 Hz display, or maybe it's just the fact that it's releasing in 2020.
If you had a phone in 2004, there's a pretty good chance it was a Motorola RAZR. The iconic phone is the tenth highest-selling of all time, and it marked the height of the flip phone era. Now that the technology has caught up, Lenovo (Motorola's parent company) is bringing it back in a big way.
One of the coolest aesthetic features of iMessage is its animated message effects. If you're like many users, you might even have discovered them by accident, where wishing your friend a "Happy Birthday!" or congratulating them on a promotion unexpectedly flooded your screen with balloons or confetti.
One of the most exciting things as an ethical hacker, in my opinion, is catching a reverse shell. But often, these shells are limited, lacking the full power and functionality of a proper terminal. Certain things don't work in these environments, and they can be troublesome to work with. Luckily, with a few commands, we can upgrade to a fully interactive shell with all the bells and whistles.
When it comes to platform games on mobile, endless runners are some of the hardest to play since they can go on seemingly forever. There's always room for improvement since your goal is to beat your previous score (or someone else's high score). But which endless running games are worth your time?
