Okay so I'm pretty sure I've completely destroyed this code. All I'm trying to do is send the user-inputted product info into a binary file to display when the user chooses the report option from the menu. I'm so confused though and I think I really screwed it up.
// ** Prototypes **
void heading(void);
int menu();
void add();
void report();
char getstring(char entry, char prompt[]);
int getint(int min, int max, char prompt[]);
double getreal(double min, double max, char prompt[]);
double total(double quantity, double amount);
double profit(double profit_cost, double profit_price);
void init_costs(double t[], int x);
void show_costs(double t[], int x);
void show(int prodnum, int prodtype, char d[], int prodquan, double cost, double price, double prod_price, double prod_cost, double prod_profit);
int menuerror(int min, int max, char prompt[]);
int prompt(char msg[]);
int quit(void);
void message(char msg[]);
char firstUpper(char *buf);
typedef struct Sports
