I can't quite understand your assignment.





It sounds to me like what you are supposed to do is collect the number of registrants for an unknown number of companies, calculate each company's cost, and output the amount for each company, plus a running total of all costs.





#include %26lt;iostream%26gt;


using namespace std;





int main () {


int registrants = 1;


double fee = 150.00;


double subtotal;


double total;


int i = 1;





while (registrants %26gt; 0) {


cout %26lt;%26lt; "Enter total number of registrants for company " %26lt;%26lt; i %26lt;%26lt; " (enter 0 to end program) %26lt;%26lt; endl;


cin %26gt;%26gt; registrants;





if(registrants %26gt; 0) {


subtotal = registrants * fee;


total += subtotal;





cout %26lt;%26lt; "Total for company " %26lt;%26lt; i %26lt;%26lt; ": " %26lt;%26lt; subtotal %26lt;%26lt; endl;


i++;


}


}





cout %26lt;%26lt; "Grand total for all companies: " %26lt;%26lt; total %26lt;%26lt; endl;





return true;


}
