// prompt user to enter discount rate

// if sale amount > 10000 then

if (sales_amount>10000){

// calculate net sales amount using formula

net_sales = ( 1 - discount_rate /100 ) * sales_amount;

// accumulate net amount

total += net_sales;  
}  // endif


// Print "Press ‘E’ to exit, others to continue" message

cout << "Enter 'E' to exit, any other character to continue...";
cin >> reply;


 // displays the total net amount with 2 decimal places

cout<<fixed<<setprecision(2)<<"Total net amount: "<<total<<endl;
cout<<"Press any key to continue…"<<endl;

// read reply

cin>> reply;

} while (toupper(reply)!='E'); //end of while loop

  cin.ignore();
  cin.ignore();
