-2
float w_, b_;

Neuron()
    : w_(2.0), b_(1.0)
{}

I dont quite understand what this means or how it works. I do get what its doing in a very vague way (seems to set variables w and b) but why and when should I use this? also why are the brackets under the data and what exactly does the : (colon) mean?

for some clarification here is the video I saw it in:

How to Build a single Neuron in C++

I'm trying to learn how to build a neural network so if any of you know any good in depth documentation on how it works please link it below as well.

    this has nothing to do with neural networks. This is just basic C++ syntax. It seems to me that the resource you are following assumes basic C++ knowledge. If that is the case I suggest either: 1. you find a resource that teaches neural networks but also assumes no C++ knowledge and explains the C++ basics along the way or 2. get the time to learn and be comfortable in C++ first then come back to neural networks in C++ or 3. choose a language you know or is easier to learn. – bolov May 24 '22 at 01:55
  • @bolov i didn't assume it had anything to do with neural networks i simply stated where i saw it for the first time. Hadn't seen it before and was just curious. but yes you are correct i do need to learn more before i dive into neural nets, but me diving into topics like this helps me find things i've never seen before such as this. You are correct though i should look for better resources! In the meantime thats what stackoverflow is for!! – Chunky Panda May 31 '22 at 23:23
