void problem
the prorgram runs but it shuts down you chose a product. can somebody look for the error?
Code:
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
void display_menu();
void tax(float);
float total = 0;
int main()
{
char choice;
display_menu();
cout << setiosflags(ios::showpoint) << setiosflags(ios::fixed) << setprecision(2);
cout << "Welcome to the Rodeo Snack Bar!" << endl;
cout << "Your current total is: $"<< total << endl;
cout << "Please enter the letter of your selection: ";
cin >> choice;
cout << endl;
switch (choice)
{
case 'S': case 's':
cout << "Sandwich - $5.00" << endl;
total+=5;
display_menu();
break;
case 'C': case 'c':
cout << "Chips - $1.50" << endl;
total+=1.5;
display_menu();
break;
case 'P': case 'p':
cout << "Pickle - $0.75" << endl;
total+=.75;
display_menu();
break;
case 'B': case 'b':
cout << "Brownie - $1.00" << endl;
total+=1;
display_menu();
break;
case 'R': case 'r':
cout << "Regular Drink - $2.00" << endl;
total+=2;
display_menu();
break;
case 'L': case 'l':
cout << "Large Drink - $3.50" << endl;
total+=3.5;
display_menu();
break;
case 'X' : case 'x':
cout << "Canceled, please start over." << endl;
total = 0;
display_menu();
break;
case 'T' : case 't':
tax(total);
break;
default:
display_menu();
}
}
void display_menu()
{
cout << endl;
cout << "S - Sandwich $5.00" << endl;
cout << "C - Chips $1.50" << endl;
cout << "P - Pickle $0.75" << endl;
cout << "B - Brownie $1.00" << endl;
cout << "R - Regular Drink $2.00" << endl;
cout << "L - Large Drink $3.50" << endl;
cout << "X - Cancel sale and start over" << endl;
cout << "T - Total the sale" << endl;
cout << "All items have additional 8.25% tax." << endl;
}
void tax(float total)
{
cout << "Sub-total: " << total << endl;
cout << "+ Tax : " << total*0.0825 << endl;
cout << "Total : " << total + (total*0.0825)<< endl;
}

That's what you tell it to do: you print the menu, get a choice, print the answer, print the menu again, then quit. Did you want something else?

will in my case it only flashes the interface. when i choose something it automatically closes!!!
i am using Dev-C++ compiler. i cant do anything with it cause it closes automatically. system pause will not do.

Stop for input at the end of main(). While waiting for input, the console window in which the program output is displayed will be visible. Once main() returns, the console window closes and is therefore invisible.
