Another win for EU users? Ads in WhatsApp won't be coming this year by David Uzondu You might have heard that ads are making their way to WhatsApp after years of the company promising it would never happen. If you are in the EU (lucky you), you won't be seeing ads until 2026 at the earliest. A new report from POLITICO confirms that Meta, which owns the messaging service, has informed Ireland's privacy regulator that the new advertising model will not roll out in the European Union for quite some time, even as it appears elsewhere in the coming months. This is not some charitable act, of course. The delay gives European regulators time to scrutinize the plan, which involves using ad preferences from linked Facebook and Instagram accounts to target users. This situation follows a pattern of other "wins" for EU users, like the changes in iOS 17.4 that finally enabled sideloading. This opened the door for alternative app stores and the (temporary) return of games like Fortnite to iPhones in the region. Similarly, we are seeing Microsoft finally back off from shoving Edge down the throats of EU users, all thanks to the Digital Markets Act. This legislation has put pressure on big tech companies to operate more "fairly" within the bloc, leading to changes that users everywhere else can only dream of for now. These regulations are precisely what companies like Apple hate. Remember, Apple has issued a warning to Australia, telling the country not to follow Europe's lead on these matters because it would create massive security and privacy risks. Apple argues that its control over the ecosystem keeps users safe, so any attempt to break that open is dangerous. The Irish Data Protection Commission will be meeting with WhatsApp to discuss the matter further. According to Commissioner Des Hogan, they plan to discuss the ad model with other European data protection authorities to gather any collective concerns. Commissioner Dale Sunderland noted that discussions with the company are "still early days", and it is too soon to identify what, if any, specific "red line issues" might exist with Meta's advertising plans. For now, Europeans can continue using their ad-free messenger, while the rest of the world prepares for the inevitable.

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!
