Whoops! That would be a problem. Also the program does not end when the user enters "S" or "s" and when I enter 3 under the number of registrants, the computer gives an error message. The program just isn't working right and I am at my wits end.

Here is the entire program:

 
int main()
{

 //declare variables
 char company = ' ';
 int registrantCount = 0;
 double chargePerson = 0.0;
 double totalCharge = 0.0;
 double averageCharge = 0.0;
 double subcharge = 0.0;
 
 //convert variable types
 static_cast <double> (registrantCount);
 cout << fixed << setprecision (2);
 
 //enter input data
 cout << "Enter company (S to stop): " << endl;
 cin >> company;
 
 //start loop
 while (company != 'S' || company != 's')
 {
   cout << "Enter number of registrants: " << endl;
   cin >> registrantCount;
   cout << endl << endl;  
  if (registrantCount > 0 && registrantCount <=3)
   subcharge = registrantCount * 150;
  else if (registrantCount > 3 && registrantCount < 10)
   subcharge = registrantCount * 100;
  else if (registrantCount >= 10)
   subcharge = registrantCount * 90;
  else
   cout << "Incorrect input" << endl;
  //end ifs
 
  registrantCount += registrantCount;
  totalCharge = totalCharge + subCharge;
  cout << "Enter next company (S to stop): " << endl;
  cin >> company;
 } //end while
 
 //calculate average
 averageCharge = totalCharge/registrantCount;
 
 //display output items
 cout << "Total number of registrants: " << registrantCount << endl;
 cout << "Total charge: " << totalCharge << endl;
 cout << "Average charge per person: " << averageCharge << endl;

 return 0;
}   //end of main function
