my loop is supposed to go until tickets available >= 0, but it stops when I have 53 tickets available. what did I do wrong?

#include ostreams using namespace std; int main() int ticketsAvail - 100, buyers = 0; int ticketssold; 1/100p until tickets are sold out while (ticketsAvail >= 0) { cout > ticketsSold; 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 buyers++; if (ticketsSold == 4) ticketsAvail = ticketsAvail - 4; else if (ticketssold 3) ticketsAvail = ticketsAvail - 3; BE else if (ticketsSold == 2) ticketsAvail = ticketsAvail 2; else if (ticketsSold == 1) ticketsAvail = ticketsAvail 1; else cout
