Array problem...

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:

c Syntax (Toggle Plain Text) 
  1. #include <stdio.h>
  2. #include <ctype.h>
  3. #include <stdlib.h>
  4.  
  5. // ** Prototypes **
  6. void heading(void);
  7. int menu();
  8. int add();
  9. int getint(int min, int max, char prompt[]);
  10. double getreal(double min, double max, char prompt[]);
  11. double total(double quantity, double amount);
  12. double profit(double profit_cost, double profit_price);
  13. double init_costs(double t[], int x);
  14. double show_costs(double t[], int x);
  15. void show(int prodnum, int prodtype, int prodquan, double cost, double price, double prod_price, double prod_cost, double prod_profit);
  16. int menuerror(int min, int max, char prompt[]);
  17. int prompt(char msg[]);
  18. int quit(void);

Look at line 179. I am guessing it is crashing here.

C Syntax (Toggle Plain Text) 
  1. for (z = 1; z < x; t++)
Do you want to increment t or z?

Yeah, I saw that and fixed it. Here is the code I have now... I run the program and it goes all the way through the first show() function, then at the continue prompt I press 'n' and it shows the show_costs table (which is completely not working btw), but it also shows the Menu in the same window again and I just want to have a "Press ENTER to continue" prompt after the show_costs table that will take the user back to the menu. Pleaaaase help me I'm running out of steam and I need to get it done or it's going to drive me crazy!

>>it isn't giving the total cost (cost * prodquan), just the cost that the user entered. I'm so close!

what function? [edit]nevermind you already told me that [/edit]

line 186: you didn't tell the program to print that information. You have to add it to your program.

Please explain this line: scanf("%lf%*c", &y); It makes no sense with the format specifier you have.
