Question
I need some help fixing my code. The code is a blackjack game and it's supposed to be a player and the dealer. The player starts out with $1000 in the bankroll. I am having some trouble getting it to subtract and add to the bankroll when the player wins and loses. It just stays at $1000.
This is the code.
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <time.h>
//function prototypes
char getachar(void);
void report(double bankroll, double bet, int gamerecord[]);
int dealing(void);
void playing(double *bankroll, double *bet, int gamerecord[]);
int facevalue(int face_value);
void beginning(double *bankroll, int gamerecord[]);
void ending(double bankroll, int gamerecord[]);
int main(void){
double bankroll = 1000;
double bet = 0;
int gamerecord[] = {0, 0, 0, 0};
char enter = 'n';
// reading saved results if any
beginning(&bankroll, gamerecord);
ending(bankroll, gamerecord);
/* playing a game */
do {
playing(&bankroll, &bet, gamerecord);
//printf("Dealing value: %d ", dealing());
//report the results;
report(bankroll, bet, gamerecord);
//quit by input
printf(" Press y to continue playing:");
enter = getchar();
}
while ((enter == 'Y' || enter == 'y') && (bankroll >= 10));
//ending();
printf(" Thanks for plying! ");
}
// void report
char getachar(void) {
char c = ' ';
/*system(*stty raw echo*);
scanf(" %c", &c);
