问题描述
我一直在使用windows中的类,但我试图运行一个基本的代码,以了解如何打开/关闭/输入/输出从Xcode文件和我通常使用的视觉工作室不工作任何想法为什么?感谢!
I've been using windows in a class I've been taking but I am trying to run a basic code to figure out how to open/close/input/output from files on Xcode and the code I usually use on visual studios isn't working any idea why? thanks!
#include <string>
#include <iostream>
#include <fstream>
using namespace std;
int main()
{
ifstream fin;
ofstream fout;
string input;
fin.open("inputFile.txt");
if(fin.fail())
cout << "File failed to open." << endl;
fin >> input;
fout.open("outputFile.txt");
fout << input;
}
推荐答案
将.txt文件放在main.cpp文件所在的目录(或任何你喜欢的目录)中。
Put your .txt files in the same directory where your main.cpp file is (or anywhere you like).
在Xcode中转到产品>方案>编辑方案>运行测试(右侧)>选项(中间顶部)
In Xcode go to Product > Scheme > Edit Scheme > Run test (on the right) > Options (middle top)
在选项检查使用自定义工作目录下,将其设置为.txt文件所在的目录。
Down under Options check "Use custom working directory" and set it to the directory where you .txt files are located.
要使用文件将必须只指定文件名,例如in_file.open(inputFile.txt);没有路径是必要的。
To work with the files, you will have to specify just file names, e.g. in_file.open("inputFile.txt"); no path is necessary.
