dice problem

i am trying to make a program to keep running (rolling of two dice) until the total of the two is 10 or 11.
which function and how can i use it to make the program stop running when the total of two dice equals 10 or 11.
i tried with the while loop but that didn't seen to work.

You may actually want to use a do-while loop here, so that the dice get rolled at least once. But either way should work. Post what you have.

here is what i have. i can not figure out how to make the program stop running when (the point) or 7 are the newTotal.
i know how to do the count loops, but how do i take the count out.

insert

Code:

---

while (count<5){

               
                rollADie=rand()%6+1;
                rollADie2=rand()%6+1;
                newTotal=rollADie+rollADie2;

                printf("The new randon is %i\n",newTotal);

                if (newTotal ==thePoint)
                {printf("You win \n");
                break;}
                else if (newTotal==7)
                {        printf("You loose\n");
                break;}
                else
                {printf("Nothing\n");}

                count++;}

---

So if you want to stop when newTotal is the point or 7, why don't you do

Code:

---

do
    /* all your dice rolling */
while (newTotal != 7 && newTotal != thePoint)
/* Check results here */

---

Remember de Morgan's law: -(x or y) = -x and -y.

Code:

---

var faces
while faces != 10 AND faces != 11
  do reroll
end while

---

The rest is basically arithmatic. And might I recommend that you use

rand() % (6 - 1) + 1

because otherwise you would occassionally get 7 on a die.

i tried that
and this is what the compiler gives me
fatal error C1075: end of file found before the left brace '{' at (the file name)

? % is remainder, so rand()%6 could only give 0, 1, 2, 3, 4, or 5.

i did that and still the same problem

When you tried ... what? The do-while? You still need to enclose the statements in the loop in curly braces.

when i click the error this is the line it takes me to
#include <stdio.h>

i got the loops, the curly braces and still the same problem

Hm, well that's right. But a normal six sided die does not have a zero face, so some effort to squeeze the range of rand into 1 to 6 inclusive is necessary. That's pretty much the only way I know how to do it also.

thats good. it works not its giving me another error
error C2061: syntax error : identifier 'rollADie2'
what does that mean

Post your code. You do have a main() function, right? And you have all your variables declared somewhere, right?

Code:

---

include <stdio.h>
#include <stdlib.h>
#include <time.h>

main(){
        int rollADie;
        int rollADie2;
        int comeOutRoll;
        int count;
        int thePoint;
        int newTotal;

        srand(time(NULL));
        count=0;
        thePoint=0;

        rollADie=rand()&#37;6+1;
        rollADieA=rand()%6+1;
        comeOutRoll=rollADie+rollADie2;

        printf("%i\n",rollADie);
        printf("%i\n",rollADie2);
        printf("%i\n",comeOutRoll);

        if (comeOutRoll == 7)
        {printf("Winner\n");}
        else if (comeOutRoll == 11)
        {printf("Winner\n");}
        else if (comeOutRoll ==2)
        {printf("You loose\n");}
        else if (comeOutRoll ==3)
        {printf("You loose\n");}
        else if (comeOutRoll ==12)
        {printf("You loose\n");}


        else
        {printf("You might have a chance \n");
        thePoint=comeOutRoll;
        printf("The point is %i\n",thePoint);
        do

                rollADie=rand()%6+1;
                rollADie2=rand()%6+1;
                newTotal=rollADie+rollADie2;

                printf("The new random is %i\n",newTotal);

                if (newTotal ==thePoint)
                {printf("You win \n");}
                else if (newTotal==7)
                {printf("You loose\n");}
                else
                {printf("Nothing\n");}

                count++;
                while (newTotal != thePoint && newTotal != 7);


        }


        printf("The answer worked\n");
        system ("Pause");
}

main must return int.

You have a rollADieA rather than a rollADie2.

And: all the statements between the do and the while must be enclosed in a set of curly braces.

Code:

---

{curly braces}

---

i fixed the rollADieA,
the problem was the curly braces.
thanx it works now
