numberGuessingGame.cpp

//Amelie Cameron Assignment 10
//This program is a classic number guessing game. The program guesses a user's number between 1 and 100. Unlike the previous assignment, this one uses a NumberGuesser class that contains all of the logic for remembering the current state of the programs guesses and implements the binary search algorithm.
