Thread: switch not working

I have a program here that is supposed to take input in the form of a number and apply it to a switch statement. For some reason no matter what my input is I always get the default case. Any help is appreciated. Thanks.

#include <iostream.h>
#include <iomanip.h>

int main()
{
int prod = 0;
double prod1 = 0;
double prod2 = 0;
double prod3 = 0;
double prod4 = 0;
double prod5 = 0;

cout.setf(ios::left);
cout << " " << setw(15) << "Product" << setw(6) << "Price" << endl;
cout << setw(3) << "\n1. " << setw(15) << "Product 1" << "$2.98" << endl;
cout << setw(3) << "2. " << setw(15) << "Product 2" << "$4.50" << endl;
cout << setw(3) << "3. " << setw(15) << "Product 3" << "$9.98" << endl;
cout << setw(3) << "4. " << setw(15) << "Product 4" << "$4.49" << endl;
cout << setw(3) << "5. " << setw(15) << "Product 5" << "$6.87" << endl;

cout << "\n\nPlease enter the number of the product for every item sold " << endl
<< "Press enter when on the blank line when done." << endl;

while ( (prod = cin.get()) != EOF )
{
switch (prod)
{
case '1':
prod1 += 2.98;
break;
case '2':
prod2 += 4.50;
break;
case '3':
prod3 += 9.98;
break;
case '4':
prod4 += 4.49;
break;
case '5':
prod5 += 6.87;
break;
default:
cout << "This is not a valid entry!" << endl;
break;
}
}

cout << "\nHere is what you got today." << endl;
cout << "Product 1: " << prod1 << endl;
cout << "Product 2: " << prod2 << endl;
cout << "Product 3: " << prod3 << endl;
cout << "Product 4: " << prod4 << endl;
cout << "Product 5: " << prod5 << endl;

return 0;
}

prod stores an integer value. '1', '2', '3', etc. are characters.

This work in C++? Can you use a string in a switch case?

Code:

using System;

class Cpp
{
	public static void Main()
	{
		string array;
		Console.Write("Enter the word 'one' or 'two': ");
		array = Console.ReadLine();
		
		switch(array)
		{
			case "one": Console.WriteLine("One is good.");
				break;

			case "two": Console.WriteLine("Two is good too.");
				break;

			default: Console.WriteLine("No, Error, SOB!");
				break;
		}		

			}
}

Troll_King, to answer your question, absolutely not. A switch statement handles a single unit of data, therefore no arrays/pointers can be used in a switch case statement.

Code:

char array[] = "hello world";
switch(array) {  //wrong!
      //stuff
}

switch(array[0]) { //this is okay
      //stuff
}

Not in C++ anyway, but you can use strings in C#.
