Just a few of the mistakes in here.
I added tolower to fix your bracket issue of malformed bracket separation
between && and || after I fixed the malformed bracket separation.
your use of default in your switch is wrong, plus it has no break in it.
read red comment inside of your code.
Code:
//#include <windows.h>
#include <stdio.h>
#include <stdlib.h>
//#include <conio.h>
#include <ctype.h> // tolower
//#include <math.h> // not needed, you're not calling any math functions
#define MOULD 3500

It'd might help if you write down your logic first in the steps of what you need to take place first then write your code to reflect same. logic board,
Code:
make menus
print menu(s)
get input
if input good
do this
if bad do that / ask again // requirement of a loop to get it to go back to asking again?
(which logic could look like this)
get input
if ( input != to what I want)
ask again
else
store input, then
go to next line (operation to get more input)
next line:
get more input
if ( input != to what I want)
ask again
else
store input then
go to next line (operation to get more input)
next line (operation to get more input)
//maybe
check to see if user wants to change mind,
if ( input == changed mine)
start all over again
else
total, print out totals.
what would be the default behavior, will their be any default behavior to determine how to
use the default check in a switch, do I even need a switch? if yes, how many?
what is required to get that done, a loop maybe? if yes how many and what type or types of loops would I need?
how many variables do I need?
what types of data will I be using, int char and any variation of same?
something like that perhaps.
the using of the key words continue and break in a loop, they are their for a reason. using break to get out of a loop when the conditions are present
is valid coding.
