Switch Statements

[MRangel]

I have looked all over the forum to find out if this switch statement is legal. I have also banged my head on the wall to try and figure this out. Can a switch statement condition be met by a range? According to my instructions I need to create a range and from that range have it go into a case. I have written something similar to what i need. Does the switch statement need a cin for it to work?

 #include <cmath>
#include <iostream>
#include <conio.h>
using namespace std;

int main ()
{
	char choice;
	double milkprice, darkprice, whiteprice, europeanprice, milk, dark, white, european, subtotal;
	double gross, discount10, discount15, discount20, discount25;

	cout << "\n\nEnter option ";
	cin >> choice;

	if ((choice >= 20) && (choice < 40))
		choice = 1;
	
	if ((choice > 40) && (choice < 60))
		choice = 2;
		
	switch (choice)
	{
			case '1':
			
				cout << "\n\nCongratulations because you purchased more than 20 dollars worth of chocolate ";
				cout << "\n you get a discount of 10% off your order!" ;
				gross = subtotal * discount10;
				subtotal = subtotal - gross;
			
				break;
			
			case '2':
			
				cout << "\n\nCongratulations because you purchased more than 40 dollars worth of choolate";
				cout << "\n you get a discount of 20% off your order!";
				gross = subtotal * discount20;
				subtotal = subtotal - gross;
	}	 
			
			
			
			
		
		
	

	return 0;
}

[long double main]

It should be case 1: and case 2:, not case '1': and case '2':.

long double main thanks for the quick reply. Your suggestion worked however, it just runs case 2 every time now regardless of the choice. Any idea why?

char choice;

If they're entering a number, I'd define choice as an integer.

Edit:

You can't use a range on a switch case, but it doesn't need a cin. Switch is looking at the value of an expression and performing different actions depending on the value.

hey wildblue,

Thanks for the help. I have been trying to do this all day I think my head is getting tired. I had them as "char" earlier and just forgot to convert it over. I understand that the switch case can't be anything but chars or ints for it to go in to its respective case. Thanks for all the help!
