Need Help Random Number Guess Game!

[KS05]

Hello,
I am having trouble with my random number guess game that I need to create for a class I am taking. It is suppose to prompt the user if they want to play the game the first time. The number of tries a user can guess is 6 and then it's suppose to prompt the user if they would like to play again after it is done. When I go through the first round everything seems to be good. However, when I hit y to play again for the second round it only allows me to enter in a number twice before it says I lose (assuming my guess is wrong) and then it prompts me to play again. I need to loop back through my do while and it doesn't seem to be doing this. I'm sure it's something small that I am missing, but I've been working on this for a few days now and just need another set of eyes! Oh and by the way I have this in a function because I am suppose to have two functions for this program but I want to get everything running right before I create the other function which will print out if the user won or lost. Can anyone tell me what I am doing wrong here?? Or does anyone have any suggestions?? If you could let me know asap, I would greatly appreciate it!

#include <iostream>
#include <ctime>
#include <cstdlib>


using namespace std;

void playGame(); //function prototype



int main()
{

playGame(); //function call


system("pause");
return 0;




}

void playGame() //Play function that asked for user input and determines if number is too high or too low from random number.
{
int guess, randomNum, numOfGuesses=0;
bool isGuessed;
char quit;


srand(time(NULL));
randomNum=rand() % 100 + 1;

isGuessed = false;

cout<<"Would you like to play a game? (y or n): ";
cin>>quit;

while(quit != 'N' && quit != 'n'){
cout<<"I'm thinking of a number between 1 and 100. Can you guess what number it is: ";
cin>>guess;
numOfGuesses ++;
do
{
if(guess < randomNum){
cout<<guess<<" is too low. Guess again. ";
cin>>guess;
numOfGuesses++;
}
else if(guess > randomNum){
cout<<guess<<" is too high. Guess again. ";
cin>>guess;
numOfGuesses++;
}
else if(guess == randomNum){
cout<<guess<<" is correct. You win and it only took you "<<numOfGuesses<<" tries"<<endl;
isGuessed = true;
}
}while((numOfGuesses < 6)&& (!isGuessed));
if(!isGuessed){
cout<<"You lose! The correct guess is "<<randomNum<<endl;
}
cout<<"Would you like to play again> (y or n): ";
cin>>quit;
while(quit != 'Y' && quit != 'y'){
cout<<"Thank you for playing!! "<<endl;
break;
}
}

}

Think about what you are doing when you restart a game.
You'll need to reset the guess count and get another random number.

On a game restart, you don't reset the guess amount. And you don't generate another random number.

Try making the loop bigger?

Hope this helps!


Edit:
You also don't need the while statement at the bottom, to cout the "Thanks for playing" message.

Simply use and if statement:

    cin>>quit;

    if(quit != 'Y' && quit != 'y')
        cout<<"Thank you for playing!! "<<endl;

If a statement only contains one line of code, you can simply add it under the statement without the use of: { and }

lol, and change the statement to:
if(quit != 'Y' || quit != 'y')
Note the && has changed to ||. If it is Y or y then you have quit asked to play again.

The problem is that when you play again you don't set numOfGuesses and isGuessed and randomNum is still the same random number as last game.

Thank you both so much! I got it now...well I have to do a little more tweaking but I got the main part! Thanks again I knew it was going to be something stupid that I was doing! lol

lol, you're welcome. I've sat here looking at my screen for hours trying to find something wrong with a program, on many occasions. The simplest thing is to leave it alone for a while, then go back and look at it. I usually find it within a short time, ahaha.
