Beginner Neural Network in C — A Tiny Perceptron That Learns OR

this example teaches:

inputs
weights
bias
weighted sum
activation function
training from examples
error correction

What is the neural network doing?

This tiny network receives two inputs:

x1
x2

It computes:

sum = x1*w1 + x2*w2 + bias

Then it decides:

if sum >= 0 → output 1
otherwise → output 0

During training:

if the answer is wrong, the weights are adjusted a little
after many examples, the network learns the rule
