VariableChangeSimulation.cpp

// VariableChangeSimulation.cpp : This file contains the 'main' function. Program execution begins and ends there.
// This is meant to simulate the scenerio where you are told to pick from N options. One of those options is correct.
// After you choose the host will reveal one of the inccorect options and then asks if you want to change your choice.
// According to the internet, changing your choice at this point increases your odds of success.
// this simulation is designed to test that.
