will it compile?

my first C++ project

try it out

[potent basin]

it works i tested it now

do u wanna test it?

Serial Designation N

[smoky turtle]

would be nice if you explained what its supposed to do

[potent basin]

this kdo is a mathematical simulation of AI, this code teaches AI to solve the problem for XOR frames, so if you compile it and add e.g. 0 1 it will give you about 1

and in summary this code can be easily converted into any other more complicated logic gate

[smoky turtle]

then you could build up on this one and make something more complicated

[potent basin]

ill try

[smoky turtle]

and document the journey

and its not really AI though, even tho everyone slaps that term on anything these days

perhaps an early and very crude version of some neural network

[potent basin]

Ok, I'll try to make some additional documentation, but I don't know if I'll have time, because I have to write the code for this network. It turned out to be something more difficult, but I never paste ready-made ones and I had to figure out how to write such code.

[smoky turtle]

code is not running away

you have all the time in the world

unless it was just a stupid school assignment and you will never pursue any other programming stuff, then this was just a waste of time

[potent basin]

no, I just have school in a few days and I also have to study for a test bro, I'm 14 years old and I've been coding in C++ for 3 years

[inner ice]

No rush then

Like deccer said you have all time in the world

[potent basin]

i know
