Explanation / Answer

Source Code:

// Example program
#include <iostream>
#include <string>
using namespace std;
int main()
{
string choice;
int ch;
int noofitems;
double totalcost;

do
{
cout<<" Would you like a sandwich,a platter or a salad ";
cin>>choice;
if(choice=="platter")
{
ch=1;
}
else if(choice=="sandwich")
{
ch=2;
}
else if(choice=="salad")
{
ch=3;
}
else
{
ch=4;
}
switch(ch)
{

case 1:

cout<<"How many platters would you like to buy ";
cin>>noofitems;

if(noofitems>=3)
{
cout<<" Each platter is $5.75";
totalcost=(5.75)*noofitems;
}
else
{
cout<<" Each platter is $6.5";
totalcost=(6.5)*noofitems;
}
cout<<" The total for platters<s> $:"<<totalcost;
break;
case 2:

cout<<"How many sandwich would you like to buy ";
cin>>noofitems;

if(noofitems>=3)
{
cout<<" Each sandwich is $2.75";
totalcost=(2.75)*noofitems;
}
else
{
cout<<" Each sandwich is $3.5";
totalcost=(3.5)*noofitems;
}
cout<<" The total for sandwich<s> $:"<<totalcost;
break;
case 3:

cout<<"How many salads would you like to buy ";
cin>>noofitems;

if(noofitems>=3)
{
cout<<" Each salads is $3.75";
totalcost=(3.75)*noofitems;
}
else
{
cout<<" Each salads is $4.5";
totalcost=(4.5)*noofitems;
}
cout<<" The total for salads<s> $:"<<totalcost;
break;
default:cout<<" Sorry we do not sell that item ";

}
}while(ch!=4);
}
