Help!!!! with my assingment

[minterman]

I need to make a menu for my class assignment. It needs to be for different products. 1. read in an order of a customer of three items. each item to have a code. need to define a variable. prints a output with a random customer number.
correct price for each order or a message sorry we dont carry this order.
here is what I came up with so far. I am lost now



#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;

int main()
{
float S,L,F,D;
total=0;
string mystring= "Welcome to Minter's Resturant";

cout << mystring << endl;
cout << "Enter S for Shrimp, L for Lobster, F for Fish, and D for Drink" << endl;
cout<< "Please enter order" << endl;

while ("S")
{ total= total+10.00;
}
else if ("L")
{ total=total+ 35.00;
}
else if ("F")
{total=total+ 6.00;
}
else if ("D")
{total=total+1.00;
}
cout << "Thank you customer ( randl)" <<endl;
return 0;
}

i'm not sure the one i done is suit with your requirement, but this is the simple example.

Next time use for your source code.

#include <iostream>
#include <string>
#include <cstdlib>
using namespace std;
 
int main()
{
     char choice;
     double total=0;
     string mystring= "Welcome to Minter's Resturant";
 
    cout << mystring << endl;
    cout << "Enter S for Shrimp, L for Lobster, F for Fish, and D for Drink" << endl;
    cout<< "Please enter order:";
 
    cin >> choice;
    switch(choice)  {
          case S:
                  total= total+10.00;
                  cout << "Your choice is: " << choice << ". And the price is $ " << total << endl;
                  break;
          case L:
                  total=total+ 35.00;
                  cout << "Your choice is: " << choice << ". And the price is $ " << total << endl;
                  break;
          case F:
                  total=total+6.00;
                  cout << "Your choice is: " << choice << ". And the price is $ " << total << endl;
                  break;
           case D:
                  total=total+1.00;
                  cout << "Your choice is: " << choice << ". And the price is $ " << total << endl;
                  break;
           default:
                  cout << "We not carry this item" << endl;
                  break;
             }
 
}
 
cout << "Thank you customer  ( randl)" <<endl;
return 0;
}

I tried to run the program and this is what I got.
I will play with it some more but thanks I am really trying to learn this class

please learn C++ with beginning a learner book.
if syntax you cant fix it yourself, then you will run into wall everytime you compile a program.
good luck.
