Well OpenGL is cross Plattform so it works on Linux too

..for windows

Mar!o

It depends on your usage. OpenGL is simpler than Direct3D11

Mar!o

And D3D12 is even more complex

Anonymous

D3D12 is a very different API (more similar to Vulkan), but D3D11 has a nice API, slightly harder than OpenGL though

Anonymous

basically, would you recommend me DirectX over opengl for windows? Are the debugging tools, performance etc.. better?

Mar!o

Yeah.

Yeah for Windows I would go with D3D11

Mar!o

Better Visual Studio integration too

Anonymous

alright

Anonymous

and if I'd make a game for Linux later, which opengl version would you recommend me? I think 2.1 is fine for most PCs

Mar!o

Yeah it's fine if you need more feature use OpenGL 3 or 4

Anonymous

I'm still thinking what API should I use (actually, I'm still undecided if make my small game cross platform)

Anonymous

since I mainly use Windows

I'll see, thanks anyways

No problem

Guys, is it possible to include a lot of libraries at the same line? Something similar to this: #include <math.h>, <stdio.h>

No, you can't I think.. The least you can do is, make a new header file and include all the headers you want there, and then including it in the file you want.

oh

Yup

How?

If you really want to achieve something similar to this, check this.

Ashish

How?

I tried to run the code and i get no error

try using the libs

why do i get No Info.plist file in application bundle or no NSPrincipalClass in the Info.plist file, exiting even tho i have https://gist.github.com/mgood7123/e20dab587ce1bb61b6bddc64cb963e58

A is an array...now I can pass A+mid1 as a parameter...

How do I acheive the same using vectors

Ravi

How do I acheive the same using vectors

A.begin()+mid1

Sandeep

A.begin()+mid1

Thanks.

Sandeep

I need to pass rest of the array

Sandeep

Like..from mid1

Ravi

Again, A.begin()+mid1+1, A.end()

Sandeep

Again, A.begin()+mid1+1, A.end()

So I need to pass two values??

Ravi

from A.begin()+mid1+1

Ravi

If to is required then A.end()

Sandeep

If to is required then A.end()

Ok thanks

Why do you flush stdin? You need to flush stdout.

hello guys

Paul Pogba

please need help

Paul Pogba

i want to crypt password on a c++ program

Paul Pogba

i want the password to crypt itself as the user is typing it 😩🙏🏼

klimi

i want the password to crypt itself as the user is typing it 😩🙏🏼

what do you mean crpyt itself as the user is typing? like it wouldn't show the characters? or that you would preview the generated hash / data?

Paul Pogba

what do you mean crpyt itself as the user is typing? like it wouldn't show the characters? or that you would preview the generated hash / data?

it should display asterics while typing

klimi

then you will need to controll the terminal, which you will ask to not print the characters, and you will have tu replace them by asterics

klimi

it should display asterics while typing

i cannot figure out how to call ObjectiveC/Swift from C++ ;-; every guide seems to be about calling C++ from ObjectiveC/Swift instead ;-;

it should display asterics while typing

or just not display anything typed at all like most pasword prompts do

use 256 bit encryption 🙂

or just encrypt it by, say adding 5 to every value 🙂

Ok, let me try and see

there is no such thing as a "fault" in encryption, only a "weak encryption" eg an encryption that can easily be broken/decrypted eg encryption via reversal can be incredibly weak if you know that reversal is the method used for encryption, thus the fault would be using reversal for encryption

Anonymous

eg plain 1234 encrypted 4321

Anonymous

tho in that case, there CAN be a fault in how a certain encryption is being implemented

Anonymous

eg if your writing your own 256 bit encryption algorithm then there WILL be faults at first (because 256 is very strong and takes years to brute force/break), and this would be very complex to implement (probably)

Anonymous

if your using an existing 256 bit encryption library than there will probably be zero faults if the library is widely used and highly recommended for use in encryption software

Need docs/ explanation for vector syntax like this: vector< vector<int>> dp(1 << n, vector<int>(n, -1)); like, it's a 2D array —> initialized with 1<<n, but cols are initialised with vector<int>(n, -1) ? :/

docs?

for these kinda usage

-1 is signed, so will be INT_MAX+1

if that helps
