Below is a program that can feel pain. It is a simulation of a programmable
2-input logic gate that you train using reinforcement conditioning.
/* pain.cpp
This 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): ";
char b1, b2;
cin >> b1 >> b2;
int input = (b1-'0')*2+(b2-'0');
if (input >= 0 && input < 4) {
int response = double(rand())/RAND_MAX < wt[input];
cout << "Output = " << response
<< ". Please enter + if right, - if wrong: ";
char reinforcement;
cin >> reinforcement;
if (reinforcement == '+')
cout << "aah! :-)\n";
else if (reinforcement == '-')
cout << "ouch! :-(\n";
else
continue;
int adjustment = (reinforcement == '-') ^ response;
if (adjustment == 0)
wt[input] /= 2;
else
wt[input] = 1 - (1 - wt[input])/2;
}
