Guess my number

[Nalrie]

I got really confuse on putting in arguments for the getUserResponseToGuess() function. I don't really know what to put into that argument. I wanted the user to think of a number in their mind, and then let the problem to guess it. But everytime I try to run my program. It didn't works out as I expected. Please help me.

the (h/l/c) means, higher, lower, and correct.

#include <iostream>

using namespace std;

int getMidpoint(int low, int high) {
	int mid = (low + high) / 2;
	return mid;
}

void getUserResponseToGuess(int guess, char& result) {
	cout << "Is it " << guess << " (h/l/c) ? ";
	if (result == 'h') {
			cout << "Is it " << getMidpoint(guess, 100) << " (h/l/c) ? ";
		}else if (result == 'l') {
			cout << "Is it " << getMidpoint(1, guess) << " (h/l/c) ? ";
		}
	}
}
void playOneGame() {
	cout << "Think of a number between 1 and 100." << endl;
	getUserResponseToGuess();

}
int main() {
	char response;

	cout << "Ready to play (y/n)? ";
	cin >> response;
	while (response == 'y') {
		playOneGame();
		cout << "Great! Do you want to play again (y/n)? ";
		cin >> response;
	}
}

This is the other version I tried again. But still not working as I expected. Please help.

#include <iostream>

using namespace std;

int getMidpoint(int low, int high) {
	int mid = (low + high) / 2;
	return mid;
}

void getUserResponseToGuess(int guess, char& result) {
	
	while (result != 'c') {
		if (result = 'h') {
			getMidpoint(guess, 100);
		}
		else if (result = 'l') {
			getMidpoint(1, guess);
		}
	}
}
void playOneGame() {
	char userInput;
	cout << "Think of a number between 1 and 100." << endl;
	cout << "Is it " << getMidpoint(1, 100) << " (h/l/c) ? " << endl;
	cin >> userInput;
	getUserResponseToGuess(getMidpoint(1, 100), userInput);

}
int main() {
	char response;

	cout << "Ready to play (y/n)? ";
	cin >> response;
	while (response == 'y') {
		playOneGame();
		cout << "Great! Do you want to play again (y/n)? ";
		cin >> response;
	}
}

I am not sure, but maybe you should be thinking about random numbers because you said you want "the user to think of a number in mind".
