如何使用Mac上的eclipse在C ++中读取和写入文件

Question

我在这里遇到一个奇怪的问题。我有一个名为input.txt的文件，我想读取该文件中的行，并将其写入名为useroutput.txt的文件中。我可以使用Visual C ++在Windows中完成。我目前正在使用eclipse，因为Visual C ++不能在mac上运行。 out文件已成功创建，但没有读取行或正在写入文件。我对C ++有点新意。有人可以帮忙吗？提前谢谢。

以下是我的代码

#include <iostream>
# include <fstream>
#include <iomanip>
using namespace std;

int main()
{
double saleAmount =0;
double ticketPrice;
int ticketsSold;

int totalTicketsSold = 0;

ifstream inFile;
ofstream outFile;

inFile.open("inputstadium.txt");
outFile.open("UserOutput.txt");

outFile<<fixed<<showpoint<<setprecision(2);

cout << "Processing data" << endl;

//1st row
inFile >> ticketPrice >> ticketsSold;
saleAmount = saleAmount + ticketPrice*ticketsSold;
totalTicketsSold = totalTicketsSold + ticketsSold;

//2nd row
inFile >> ticketPrice >> ticketsSold;
saleAmount = saleAmount + ticketPrice*ticketsSold;
totalTicketsSold = totalTicketsSold + ticketsSold;

//3rd row
inFile >> ticketPrice >> ticketsSold;
saleAmount = saleAmount + ticketPrice*ticketsSold;
totalTicketsSold = totalTicketsSold + ticketsSold;

//4th row
inFile >> ticketPrice >> ticketsSold;
saleAmount = saleAmount + ticketPrice*ticketsSold;
totalTicketsSold = totalTicketsSold + ticketsSold;

outFile << "Number of Tickets sold = " << totalTicketsSold<<endl;
outFile << "saleAmount = $ " << saleAmount<< endl;

inFile.close();
outFile.close();

return 0;

}
