C++流找不到相对路径

C++ fstream Won't Find Relative Path

本文关键字：路径 相对 找不到 C++      更新时间：2023-10-16

问题在下面。我使用的是Microsoft Visual Studio and Admissions.txt与.cpp，.h和.sln文件的文件夹中，但该程序找不到相对路径。明确说明路径也行不通。我只是关心现在让ifstream现在正常工作。

/*
A new aquarium just opened up and your boss would like you to write a short program that allows him / her to calculate the number of tickets sold and money brought in for ticket sales.
There are different types of tickets you can buy : All - Access, Gold, and Silver.
The data for ticket sales will be stored in the file admissions.txt with the following format where the first column represents the ticket cost and the second the number of tickets sold.
150.00 89
56.50 300
45.25 450
The first line indicates that the ticket price is $150.00 and that 89 tickets were sold at that price.Output the total number of tickets sold and the total sale amount for ALL tickets.Format your output with two decimal places.
Sample input file :
226 1761
153 28513
62 35779
*/
include fstream
include iostream
include string
using namespace std;

int main()
{
    ifstream inFileData;
    string line1;
    string line2;
    string line3;
    inFileData.open("admissions.txt"); //contains sample input
    inFileData >> line1;
    inFileData >> line2;
    inFileData >> line3;
    cout << line1;
    cout << line2;
    cout << line3;
    inFileData.close();
    system("pause");
    return 0;
}

您可以使用此程序生成测试文件。无论何时生成所述文件，您的输入文件都必须是。就我而言，它相对于VS调试器的.vcxproj，并且在使用.EXE时与.EXE相同的目录。

#include <iostream>
#include <fstream>
int main() {
    std::ofstream file("relative_path_test.txt");
    if (file.is_open()) {
        file << "Test file";
    }
    file.close();
    return 0;
};

向您的程序中添加system("dir")，以查看程序运行时所处目录的路径。从那里您应该能够弄清楚文件的正确路径是什么。
