Thread: Need Help With a BlackJack Program in C

Can anyone help me get started on this program, i have started it lightlybut seem to get a bit confused there after when i have to begin adding in new functions. The out put for this should look like this:

Enter card (1-13): 1
Enter card (1-13): 10
Total(s): 11, 21
Enter dealer's total: 21
TIE

Another game (1:Yes/0:No): 1
Enter card (1-13): 11
Enter card (1-13): 1
Total(s): 11, 21
Enter dealer's total: 17
YOU WON!!

Another game (1:Yes/0:No): 1
Enter card (1-13): 10
Enter card (1-13): 12
Total(s): 20
Another card (1:Yes/0:No): 0
Enter dealer's total: 22
YOU WON!!

Another game (1:Yes/0:No): 1
Enter card (1-13): 10
Enter card (1-13): 8
Total(s): 18

Another card (1:Yes/0:No): 0
Enter dealer's total: 20
YOU LOST!!


Another game (1:Yes/0:No): 1
Enter card (1-13): 1
Enter card (1-13): 1
Total(s): 2, 12

Another card (1:Yes/0:No): 1
Enter card (1-13): 9
Total(s): 11, 21
Enter dealer's total: 17
YOU WON!!

Another game (1:Yes/0:No): 1
Enter card (1-13): 2
Enter card (1-13): 3
Total(s): 5

Another card (1:Yes/0:No): 1
Enter card (1-13): 3
Total(s): 8
Another card (1:Yes/0:No): 1
Enter card (1-13): 2
Total(s): 10

Another card (1:Yes/0:No): 1
Enter card (1-13): 4
Total(s): 14
Another card (1:Yes/0:No): 1
Enter card (1-13): 3
Total(s): 17
Another card (1:Yes/0:No): 0
Enter dealer's total: 17
TIE

Another game (1:Yes/0:No): -1
Error! Enter 1 for yes or 0 for no.
Another game (1:Yes/0:No): 2
Error! Enter 1 for yes or 0 for no.
Another game (1:Yes/0:No): 1
Enter card (1-13): 0
Error card must be between 1 and 13!
Enter card: 14
Error card must be between 1 and 13!
Enter card: 8
Enter card (1-13): 2
Total(s): 10
Another card (1:Yes/0:No): -1
Error! Enter 1 for yes or 0 for no.
Another card (1:Yes/0:No): 2
Error! Enter 1 for yes or 0 for no.
Another card (1:Yes/0:No): 1
Enter card (1-13): 1
Total(s): 11, 21
Enter dealer's total: 20
YOU WON!!
Another game (1:Yes/0:No): 0


i dont have much as of yet but here is what i have so far:

Code:

#include <stdio.h>


main()
{
int total;
int card1, card2;
int dealer;



        total = 0;

        printf("Enter Card (1-13): ");
        scanf("%d", &card1);
        printf("Enter Card (1-13): ");
        scanf("%d", &card2);
        total = card1 + card2;
        printf("Total(s): %d\n", total);
        printf("Enter Dealer's Total: ");
        scanf("%d", &dealer);

}

and required functions i need to be used are :
int validateCard();
int value(int card);
void endResult(int Lost,highest total);
int anotherCard();
void totals(int total, int numAces, int *pLost, int *pHighestTotal);


your help would be greatly appriciated!!

So what's your question? plz email me teh codez?

which codes? like what i need to do?

Well... Write code, I'd guess...

well my question is basically how do i get started using the functions i posted in the initial thread? i get screwed up also because when the card is 1 it is suppose to be ACE which can be 1 or 10 so i have to total it twice....and then ask the user if they would like another card

Well, the names of the functions are clear indicators for what they should do, so what's keeping you from writing them?
And the ace having 2 possible values is the entire reason of having the number of aces as a parameter in the total function.

ok thanks,

ok so this is what i have created so far but i cant get it to compile yet, i still have a couple functions to add.... any suggestions as to what i am doing wrong so far??

Thanks,

Code:

#include <stdio.h>
int validateCard();
int value(int care);
void endResult(int Lost,highest total);
int anotherCard();
void totals(int total, int numAces, int *pLost, int *pHighestTotal);


main()
{
int card1, card2, total, dtotal;

printf("Enter card: \n");
scanf("%d" , &card1);
printf("Enter card: \n");
scanf("%d" , &card2);

validateCard(card1, card2);

total = card1 + card2;

printf("%d" , total);

printf("Enter dealer total: \n");
scanf("%d" , &dtotal);

endResult(total, dtotal);



int validateCard(*c1, *c2){
if (card1 > 10)
card1 = 10;
if (card2 > 10)
card1 = 10;
}


void endResult{
if (total > dtotal)
printf("You Win");

else if(dtotal > total)
printf("You Lose");

else
printf("Tie");
}

}

i realize noone is going to write the code for me,
but i dont quite understand what you suggested either, could you clarify it a bit?

You have a function,

validateCard(*c1, *c2)

You have told the compiler that function will be like this:

int validateCard()

The actual function doesn't have a return, (but might return an int, that part is not specified), and has parameters of two pointers, going into it.

Your prototype says the function will return an int, and has either no parameters going to it, or possibly one integer, you again, have not specified it correctly.

You need the actual function, and the function's prototype, to be the same:

either:

void validateCard(int*, int*) or
int(validateCard(void)
or whatever you want it to be, but it needs to have the same return type (or no return), and the same parameters.
