Hi guys,
Ok so I need to use pointer syntax for the functions init-costs(), show-costs() and toUpper() in the following code. I'm still working on the first two, but I'm curious as to what needs to be done to the toUpper() function. I'm pretty sure I've already done the pointer syntax correctly, right? Here is the code:
#include <stdio.h>
#include <stdlib.h>
#include <ctype.h>
#include <string.h>
/* ================================================================== */
// ** Prototypes **
void heading(void);
int menu();
int add();
void 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[]);
void firstUpper(char *buf);
