Hi guys,
Ok so once again, I have pretty much the whole code written, but something is not working right! When I run it and select "add record", it works up until the user inputs price, then it just prints a ton of numbers and basically crashes. Please help me figure out what is wrong!
Here is the code:
#include <stdio.h>
#include <ctype.h>
#include <stdlib.h>
// ** Prototypes **
void heading(void);
int menu();
int add();
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);
double init_costs(double t[], int x);
double show_costs(double t[], int x);
void show(int prodnum, int prodtype, 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[]);
// ** Functions **
int main()
{
int TRUE = 1;
int FALSE = 0;
int select, end = TRUE;
do
{
select = menu();
switch (select)
{
case 1: add(); break;
case 2:
case 3:
case 4:
case 5: end = quit(); break;
default: message("\n\nPlease make a selection between 1 and 5.\a");
}
}
while (end);
return 0;
}
