Apple iOS 26 beta has a hidden iPhone ringtone by Aditya Tiwari If you're waiting for a new iPhone ringtone to attend your calls, Apple might be baking something for this year. The recently announced iOS 26 update hides a new ringtone for iPhone, discovered in the source code of its first developer beta. Details about the new iPhone ringtone called "ReflectionAlt1-EncoreRemix" were posted on the social media platform X by @8810cfw. It was later re-shared by known Apple leaker @ShrimpApplePro and confirmed by @aaronp613. Looking back a few pages in tech history, Apple's ringtone journey began with the first iPhone in 2007. The Cupertino giant included the classic Marimba ringtone as default, which became a signature for Apple fans. Since then, Apple has continued to release new ringtones and system sounds over the years. However, it exerted more control over iPhone ringtones during the initial years. In addition to the ringtones preloaded on iPhones, Apple also allows users to buy new ringtones from the iTunes Store app. Users can also create their own custom ringtones from an audio file or a song from Apple Music using the GarageBand app. Not just Apple, tech companies have long used ringtones as a way to differentiate their devices from the rest. This includes the fallen warrior, Nokia, and newer competitors like the Google Pixel, which got a new Sound Matters collection last year. The unreleased iPhone ringtone isn't directly available to users in the Settings app as part of the developer beta. It's an alternative version of the Reflection ringtone that has been present on iPhones as the default since 2017. While it's being speculated that the ringtone could be exclusive to this year's iPhone 17 series, it's unclear if Apple will include it in upcoming iOS 26 beta releases. Apple will release the iOS 26 update later this year, featuring a range of new features, including a revamped Photos app, new iPhone wallpapers, and the Vista-like Liquid Glass design. Its public beta is expected to arrive sometime during the next month. -

This article is about the start menu not the start button -

This is why I wasn't really annoyed with Windows 8's full screen Start. Since Vista I launch programs by quickly pressing the WIN key and typing first few letters of whatever it is I need. Honestly, my personal equivalent of the Start menu is the WIN+X menu - it truly contains some useful things I do not feel like typing into Search. -

No and no. Didn't read the article but my take is they should remove the start menu altogether and replace it with Powertoys Run

Question
coolbunny1234
As I do on most forums that I join, I usually post a series of tutorials for programming, specifically C++. I'll be creating tutorials at random or by request, and usually cover most of the basics, advancing into intermediate programming and later scratching the surface of more advanced programs.
This tutorial assumes you have basic, minimal knowledge of C++.
What you will need:
And that's it! I currently use Visual Studio 2013 Professional, I got it for free via Dreamspark (if you're a college student like myself, go grab it now) or download the evaluation software.
http://www.visualstudio.com/downloads/download-visual-studio-vs
Now for the tutorial! This program is a simple program that asks the user to specify the amount of grades you want averaged and summed. It then asks for the actual grade of each, followed by the logic of average/sum of the user specified grades.
Step 1
Open Visual Studio, and click File > New Project. A pop up window will appear, and on the left hand tab, select Visual C++, and then Win32 Console Application.
A screen will appear, click next, but do not click finish on the next screen!
Before clicking Finish, make sure you check off the box that says "Empty Project"
Next, Click the tab Project > Add New Item
A screen will appear like this one, chose the .cpp and name it whatever you'd like. This file is the source code file for your program.
You now have a blank workspace for your program, time to dive into the language.
Step 2
We're now going to add the file headers to the source. There are many functions and inputs in the language of C++, and these headers allow us access to them so we don't have to code them individually in each program. I.e the function "cout" , or command output, allows us to print whatever we want on screen.
So go ahead and add these file headers.
And here's an image for the visual learners of what it should be so far.
Step 3
After we add the headers, we need to initiate a start up function, and the default function that's called when a program is ran is int main(). Your entire source for your program, or the entire logic of the program, is within these parameters.
(I'll be adding code to previous code so it's chronological and makes more sense).
Boom! This is our entire program. Within those brackets, you can do whatever, such as say hello..
And if you ran this, it would create a program that says Hello Neowin. Simple, helloworld crap.
Step 4
However, we want to create a program that does averages/sums of user specified input. So how do we do that?
First, we're going to need to init and double a few variables.
The variables above are as follows:
Step 5
We now need to have the program ask the user how many grades are going to be inputted.
Let's break this down a little if you're lost. Currently, the code above simply is going to print out on screen "How many grades are you going to enter?", and n_grades will record whatever number you input.
Step 6
Now for the hardest part of the program. How are we going to code something that gives the user infinite amount of options (how many grades he can input... 1- infinity)? This is where the for loop comes in handy. I'm going to post the code first, then explain.
As you can see, the for loop above does it all for us. If you can't see however, read on. The first line of the loop
Simply inits the variable count, which we use to determine how many times we ask the user to enter a grade, based on his input before. Then, if count is less than or equal to n_grades, then we increment count by one, or count++.
Within the loop, we also take care of the math part of figuring out the sum of the grades, using
which is the same as
Step 7
The rest of the program is a cruise from this point on. We just need to to the math logic for the average, and output the results!! I'll post the full source below, as I've got to finish this up quickly.
And voila! We have a simple program that allows us to find the average and the sum of a user specified number. Sorry for the shortness and briefness of the tutorial, gotta run out the door as we speak. Let me know any areas that could be improved, tutorial wise or code wise. Thank you!
