Here is a program that feels pain. It is a simulation of a 2-input logic gate
that you train by reinforcement learning. It "feels" in the sense that it
adjusts its behavior to avoid negative reinforcement from the user.
/* pain.cpp - A program that can feel pleasure and pain.
The program simulates a programmable 2-input logic gate.
You train it by reinforcement conditioning. You provide a pair of
input bits (00, 01, 10, or 11). It will output a 0 or 1. If the
output is correct, you "reward" it by entering "+". If it is wrong,
you "punish" it by entering "-". You can program it this way to
implement any 2-input logic function (AND, OR, XOR, NAND, etc).

#include <iostream>
#include <cstdlib>
using namespace std;
int main() {
// probability of output 1 given input 00, 01, 10, 11
double wt[4]={0.5, 0.5, 0.5, 0.5};
while (1) {
cout << "Please input 2 bits (00, 01, 10, 11): ";

cout << "ouch! :-(\n";
