Hi-Lo Game Problem

[DragonOsman]

I'm having trouble with this game; the random number picked by the computer constantly changes during the same run of the game.

#include <iostream>
#include <cstdlib>
#include <ctime>
#include "keep_window_open.h"

int getRandomNumber(int min, int max);
void playHiLo(char answer, int count, int guess, int randomNumber);
char playAgainOrNot();

int main()
{
	using namespace std;

	srand(time(0));
	rand();

	char answer = ' ';
	int count = 0;
	int guess = 0;
	int randomNumber = 0;

	cout << "Let's play a game. I'm thinking of a number. You have 7 tries to guess what it is.\n";
	playHiLo(answer, count, guess, randomNumber);
	keep_window_open();
	return 0;

}

int getRandomNumber(int min, int max)
{
	static const double fraction = 1.0 / (static_cast<double>(RAND_MAX) + 1.0);
	return static_cast<int>(rand() * fraction * (max - min + 1) + min);
}

void playHiLo(char answer, int count, int guess, int randomNumber)
{
	using namespace std;
	
	do
	{
		randomNumber = getRandomNumber(1, 100);

		cout << "Guess # " << ++count << ": ";
		cin >> guess;
		cin.ignore(32767, '\n');

		if (guess == randomNumber)
		{
			cout << "Correct! You win!\n";
			answer = playAgainOrNot();
			if (answer == 'n')
			{
				break;
			}
		}
		else if (guess > randomNumber)
		{
			cout << "Your guess is too high.\n";
		}
		else if (guess < randomNumber)
		{
			cout << "Your guess is too low.\n";
		}

		if (count == 7)
		{
			cout << "Sorry, you lose. The correct number was " << randomNumber << ".\n";
		}
	} while (guess != randomNumber && count < 7);
}

char playAgainOrNot()
{
	using namespace std;
	char answer;
	do
	{
		cout << "Would you like to play again (y/n)?";
		cin >> answer;
		cin.ignore(32767, '\n');
	} while (answer != 'y' || answer != 'n');

	if (answer == 'y')
	{
		cout << "Let's play a game. I'm thinking of a number. You have 7 tries to guess what it is.\n";
	}

	return answer;
}

For reference, I'll also post the keep_window_open.h header and the .cpp file that goes with it.

header:

#ifndef KEEP_WINDOW_OPEN_H
#define KEEP_WINDOW_OPEN_H

void keep_window_open();

#endif 

.cpp file:

#include <iostream>

void keep_window_open()
{
    using namespace std;
    cin.clear();
    cout << "Please enter a character to exit\n";
    char ch;
    cin >> ch;
	cin.ignore();
}

I use rand() once in main() before calling the random number generation function because I'm using VS Community 2015 and I apparently need to discard the result from rand() once before using it normally because of a flaw in the implementation for rand() in VS.

Take a look at your do-while loop from lines 39-69.

Yes, your loop is calling the random number generator every single iteration, therefore changing your number. So, instead, put the variable outside the loop
