Question

I use fstream to read/write file in C++.
The structure of my project is:

project
    /folder
        source.cpp
        source.o
        source.out
        data.txt
        Makefile

My code to read file look like this:

ifstream f;

f.open("data.txt"); // because source.out is same directory with data.txt

But it can’t read this file if I run it in Eclipse. It only work if I put data.txt file like this:

project
    /folder
        source.cpp
        source.o
        source.out
        Makefile    
    data.txt

It’s not good. I also don’t want to fix my code to:

f.open("folder/data.txt")

when they are in same directory. Because if I run source.out outside eclipse, it doesn’t work.

Anybody can give me some solutions?

You can set the “working directory” in the run configuration (arguments tab)
