c++ - 如何在 Mac 上使用 eclipse 在 C++ 中读取和写入文件

Question

我在这里遇到了一个奇怪的问题。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 中做到这一点。我目前正在使用 eclipse，因为 Visual C++ 无法在 mac 上运行。输出文件已成功创建，但没有读取行或正在写入文件。我对 C++ 有点陌生。有人可以帮忙吗？提前致谢。

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;

}
