@Tero Blame windows

You need admin access to install there

kek

```One of the benefits of installing to Program Files is that is exactly where the user expects it to go. 
The biggest downside is that the user needs administrative privileges, which isn't always required by the program.```

Ain't nobody got time for that

i actually don't know why installing to program files requires admin

do things there have special privileges?

I know 20 year old electronics graduates that won't install an altium product if it pops up windows utc

lol

how do i avoid getting scope fucked in c++

if i have an if statement

to store a smaller or larger int

but then i want to use those variables globally

maybe extern keyword could help?

not sure, I've only done arduino C++, but that's how I usually do it

BJ's PPP has some prank questions, like it gives questions that require knowledge of scope and list sorting before it teaches you it

avoid global variables for most purposes

globals are fine as long as properly named and it has few setters (ideally, it's just set in one place, once)

having used threads a bit it's abundantly possible to make the kinds of errors people supposedly cause with globals by referencing an object or variable with multiple threads

`Although threads seem to be a small step from sequential computation, in fact, they represent a huge step. They discard the most essential and appealing properties of sequential computation: understandability, predictability, and determinism.`

(this is probably where functional fans come in and tell everyone about how having any shared state is bad)

for some reason this program returns x as 25 million times its number

#include <iostream>
#include <string>
#include <vector>
#include <algorithm>
#include <cmath>
using namespace std;
inline void keep_window_open(){ char ch; cin>>ch; }

//for some reason, the square function returns 25 million
int square(int x)
{
x +=x;
cout << x;
}

int main()
{
int i = 0;

cout << "Enter a value.\n\n";
cin >> i;
cout << square(i);
}

seeing all these double >> around are you sure you're not bitshifting something?

i don't actually know C++ though

@Tero that's how you print in c++

And take input

In C++ the '>>' and '<<' indicator data flows with iostream

ok

why's it returning wrong results if not bitshifting then

Why use '+=' here @What Would Jack Conte Do? ?

I don't get the point of the cout in the function

Hmm, that could be something, nesting Couts in the return sequence

Why not ```return x;```?

He's already imported the cmath library, so why didn't he use the pow() function?

both good questions

so apparently the int-returning function square with no return statement results in undefined behaviour

sure do love C/C++
