The manager of a football stadium wants you to write a program that calculates the total ticket sales after each game. There are four types of tickets—box, sideline, premium, and general admission. After each game, data is stored in a file in the following form:

ticketPrice numberOfTicketsSold
...
Sample data are shown below:
250 5750
100 28000
50 35750
25 18750

The first line indicates that the ticket price is $250 and that 5750 tickets were sold at that price. Output the total number of tickets sold and the total sale amount into an output file. Format your output with two decimal places. (You are required to generate an output file that has the results.)

So far my answer is

#include

#include

#include

using namespace std;

int main() {

double total = 0;

int nTickets = 0;

std::ifstream infile("tickets. txt");

int a, b;

while (infile >> a >> b)

{

total = a*b;

nTickets = nTickets + b;

}

cout << "Total Sale amount: " << total << endl;

cout << "Number of tickets sold: " << setprecision(2) << nTickets << endl;

system("pause");

return 0;

}
