#include <iostream>
using namespace std;

int main(){

	for (int i = 0; i < 1000; i++) {

	int die1, die2, roll1, roll2, point,;

	die1 = 1 + rand() % 6;
	die2 = 1 + rand() % 6;
	point = die1 + die2;
	

	cout << "You rolled: " << point << endl;

	if( point == 7 || point == 11 )
	{
		cout << "You win! Would you like to play again? ";
	}

	else if( point == 2 || point == 3 || point == 12 )
	{
		cout >> "Sorry you lose. Do you want to play agin? ";
	}

	return 0;
}

I got till here. I am getting lots of errors. I can only use the iostream, nothing else. I also need to let the player continue playing. Any help, please?

You should look at http://www.daniweb.com/forums/thread264097.html.

You have the same problems as that guy.

Also, line 8 has an error.

Also, i am always getting 12. Why's that?

I'm not 100% sure how rand() works, but I know that if it's not 'seeded' to time (someone else can explain that term I think) it will always produce the same pattern of random numbers. It's pseudo random.

See this thread: http://www.daniweb.com/forums/thread259974.html

For the other problem: http://www.daniweb.com/forums/thread261366.html

Put the code in a loop.

As for the 12, you need to look up the srand() function.

- You need srand to seed your random number generator, otherwise you will ALWAYS get the same number unless you restart the program.
- Format your code a bit better. A shortcut to do this is:
ctrl + a
alt + F8
- To restart the whole function use a do-while loop. Avoid gotos.

Think about it. Don't expect us to hand you all the answers. What loop makes sense?

Thanks alot guys! I got the srand to work. But now, i need to know how to keep the player to continue playing if he wants to.

Which loop should i use? Any help is appreciated.

//

#include <iostream>
#include <time.h>
using namespace std;

int main(){
	

	int die1, die2, point;
	
	
	srand (time (NULL));

	die1 = 1 + rand() % 6;
	die2 = 1 + rand() % 6;
	point = die1 + die2;
	

	cout << "You rolled: " << point << endl;
	
	if( (point == 7) || (point == 11) )
	{
		cout << "You win! Would you like to play again? Enter y to play again. ";

	}

	else if( (point == 2) || (point == 3) || (point == 12) )
	{
		cout << "Sorry you lose. Do you want to play agin? ";
	}

A while loop?

I got till here. But there is something infinite going on.

	while( point== 7 || point == 11 )

How do you exit the loop?
Do you want to roll the dice once then loop or do you want to roll the dice in the loop?

I repeat -- do you want to roll the dice only once in your program or for each turn?

khaled.s 0 Newbie Poster · Answer 11 · 2010-03-03T08:28:18+00:00

For each turn.

I got till here.

But the problem is when i hit y, it just goes to an infinite loop showing the same number.

//

#include <iostream>
#include <time.h>
#include <iostream>
using namespace std;

int main(){
	
	char playagain;
	int die1, die2, point;
	
	
	srand (time (NULL));
	die1 = 1 + rand() % 6;
	die2 = 1 + rand() % 6;
	point = die1 + die2;
	
	cout << "You rolled: " << point << endl;

	
	if( point == 7 || point == 11 )
	{cout << "You win! Would you like to play again? Enter y to play again.   ";
	cin >> playagain;}
	else if ( point == 2 || point == 3 || point == 12 )
	{
		cout << "You lose. Would you like to play again? Enter y to play again.   ";
		cin >> playagain;
	}
	else
		cout << "Want to play again?";
		cin >> playagain;

	while ( playagain == 'y' )
	{
		cout << "You rolled: " << point << endl;
	}


		

	
	
		
	
	return 0;
}

WaltP 2,905 Posting Sage w/ dash of thyme Team Colleague · Answer 12 · 2010-03-03T08:35:44+00:00

Think. Where is your input? Where is your loop? Is your loop in the correct place?

I repeat -- Think! It's important when you write code.

khaled.s 0 Newbie Poster · Answer 13 · 2010-03-03T08:38:47+00:00

Should i put it at the top? Before the input? Can you point that out to me?

Also, am i close to finishing it? Or do i still have a lot of work to do?

khaled.s 0 Newbie Poster · Answer 14 · 2010-03-03T08:40:24+00:00

I get this, the variable 'playagain' is being used without being initialized. What's wrong?

Stop answering a question with a question. The answer to my question is a simple yes or no. And if you answer that simple question, you will be closer to knowing what to do once you think about it.

I get this, the variable 'playagain' is being used without being initialized. What's wrong?

The first time you use playagain you are testing it. But what is it's value before that? It could be anything. You need to start it out with a value.
