C programming Dice game problem?

[jobypollard]

Hey everybody.
I'm working on a dice game using C. You roll two dice (Red and Blue). If you roll doubles, you get points. For doubles of 1 or 6, you get ten points. For doubles 2-5, you get 5 points.
My problem is, whenever I execute the game, I only ever get 0 points even when I get doubles (of anything).

Help please?
Here's the code:

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

#define ROLL_DIE ((rand() % 6) +1)

int main(void)
{ int RedDice ;
int BlueDice ;
int Points ;

srand(time(NULL));
printf("Rolling Dice\n" );


printf ("Red Dice is %d\n", RedDice=ROLL_DIE);
printf ("Blue Dice is %d\n", BlueDice=ROLL_DIE);
if (RedDice ==6 && BlueDice == 6 )
{Points = Points +10;
if (RedDice ==1 && BlueDice ==1 )
Points = Points + 10;
if(RedDice == 2 && BlueDice == 2 )
Points = Points +5;
if(RedDice == 3 &&BlueDice == 3 )
Points = Points +5;

if(RedDice == 4 &&BlueDice == 4 )
Points = Points +5;
if(RedDice == 5 && BlueDice == 5 )
Points = Points +5;
}

printf("You have %d points\n", Points);

return(0);

}

It is always good programming practice to initialize your variables when they are declared. With your code, I got this output:

Code: Select all

me@dev-box:~/Desktop/dice$ ./dice
Rolling Dice
Red Dice is 1
Blue Dice is 3
You have 32767 points


There are plenty of resources online to learn more about programming. It can be tricky at first but you'll get the hang of it if you try hard enough

Try this out:
Compile in terminal and then run program

Code: Select all

gcc -o dice dice.c
./dice


dice.c

Code: Select all

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

#define ROLL_DIE ((rand() % 6) +1)

int rollDice(void)
{
    int Points = 0;
    int RedDice = ROLL_DIE;
    int BlueDice = ROLL_DIE;

    if(RedDice == BlueDice)
    {
        if(RedDice <= 0 || RedDice > 6)
        {
            printf("Dice out of range: %d\n", RedDice);
            return(0);
        }
        else if(RedDice == 1 || RedDice == 6)
            Points = 10;
        else
            Points = 5;
    }
    printf("Red: %d, Blue: %d, Points: %d\n", RedDice, BlueDice, Points);
    return(Points);
}

int main(void)
{
    int TotalPoints = 0;
    int Times = 3;       /* Let's roll 3 times */
    int i = 0;           /* used for looping */

    srand(time(NULL));

    printf("Rolling Dice...\n" );
    for(i = 0; i < Times; i++)
    {
        printf("Roll #%d ", i+1);
       
        TotalPoints += rollDice();
    }

    printf("You have %d total points\n", TotalPoints);
    return(0);
}
