Write a e a program that plays a number guessing game with a Human user. The Human user will think of a number between LOWER LIMIT and UPPER LIMIT, inclusive. (LOWER LIMIT and UPPER LIMIT will be global constants, typically 1 and 100, but your program must still work if they are set to so different. You may assume that LOWER LIMIT < UPPER LIMIT.) The program will make guesses and the user will tell the program to guess higher or lower. A sample run of the program might look like this: Ready to play (y/n)? Think of a number between 1 and 100. My guess is 50. Enter 1 if your number is lower, h if it is higher, 'e' if it is correct: My guess is 75. Enter 1 if your number is lover, h if it is higher, 'e' if it is correct: h My guess is 88. Enter 1 if your number is lower, 'h' if it is higher, 'e' if it is correct: 1 My guess is 81. Enter 1 if your number is lower, 'h' if it is higher, 'e' if it is correct: e Great!

Write a program that plays a number guessing game with a Human user. The Human user will think of a number between LOWER_LIMIT and UPPER_LIMIT, inclusive.

The program will make guesses and the user will tell the program to guess higher or lower. A sample run of the program might look like this: Ready to play (y/n)? y Think of a number between 1 and 100. My guess is 50. Enter '1' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 75. Enter '1' if your number is lower, 'h' if it is higher, 'c' if it is correct: h My guess is 88. Enter '1' if your number is lower, 'h' if it is higher, 'c' if it is correct: 1 My guess is 81. Enter '1' if your number is lower, 'h' if it is higher, 'c' if it is correct: c Great! Do you want to play again (y/n)? y Think of a number between 1 and 100. My guess is 50. Enter '1' if your number is My guess is 25. Enter '1' if your number is My guess is 37. Enter '1' if your number is lower, 'h' if it is higher, 'c' if it is correct: c Great! Do you want to play again (y/n)? n The strategy that the program will use goes like this: Every time the program makes a guess it should guess the midpoint of the remaining possible values. Consider the first example above, in which the user has chosen the number 81: On the first guess, the possible values are 1 to 100. The midpoint is 50. The user responds by saying "higher" On the second guess the possible values are 51 to 100. The midpoint is 75. The user responds by saying "higher" lower, 'h' if it is lower, 'h' if it is On the third guess the possible values are 76 to 100. The midpoint is 88. The user responds by saying "lower" On the fourth guess the possible values are 76 to 87. The midpoint is 81. The user responds "correct" Additional Requirements int main() { The purpose of the assignment is to practice writing functions. Although it would be possible to write the entire program in the main function, your solution should be heavily structured. Most of the point penalties given on this assignment will be for not following the instructions below carefully. The main function must look exactly like this. Copy and paste this code into your file, and don't edit it: char response; cout << "Ready to play (y/n)? "; cin >> response; higher, 'c' if it is correct: 1 higher, 'c' if it is correct: h while (response == 'y') { playOneGame ( ) ; cout << "Great! Do you want to play again (y/n)? "; cin >> response; } The playOneGame() function must implement a complete guessing game using the range LOWER_LIMIT to UPPER_LIMIT. In addition, you must implement the following helper functions to be invoked inside your playOneGame() function: void getUserResponseToGuess(int guess, char& result) The getUserResponseToGuess() function should prompt the user to enter 'h', 'I', or 'c' (as shown in the sample output). It should set its "result" parameter equal to whatever the user enters in response. It should do this ONE time, and should not do anything else. Note that printing the guess is part of the prompt. int getMidpoint (int low, int high) The getMidpoint() function should accept two integers, and it should return the midpoint of the two integers. If there are two values in the middle of the range then you should consistently chose the smaller of the two.
