Files Continually Fail to Open in Multiple Programs

Question

For the last week, I've not been able to open files in Xcode. I'm looking to learn why it isn't working, and how to fix it.

I've posted two questions in stack overflow here and here, and received good advice, but no solution.

Additionally, I have another program here which opens files just fine with no issues... I have no idea why one is opening files, and the other isn't. (Reminder, NONE of my recent programs are opening files.)

{Update: checking above program before this post, NOW it fails, saying the files don't exist... This program was running yesterday and I made no changes to it. I promise it was working... So why am I having file issues suddenly?}

Just to be sure, I've:

Gone to Build Phases >> Copy Files >> Add File, adding both files to Absolute Path
Checked the spelling of the files and my code

Here is a simple program that should open a text file, then print the contents, which are "testing 1 2 3" - except it doesn't:

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main() {

    fstream inFile;

    string words;

    inFile.open("test.txt");
    if (!inFile) {
        cout << "Failure." << endl;
        exit(1);
    }

    getline(inFile, words);

    cout << words << endl;


    return 0;
}

This program fails every time (as do my others).

Here is my output:

Failure.

Program ended with exit code: 1

Setting a breakpoint at the statement inFile.open("test.txt");, I get:

@AndersKarlsson, thanks - it worked in the above program... I don't want to declare success until I've tested this in all my programs. I'll update later today. — NonCreature0714, Dec 05 '15 at 13:11
@AndersKarlsson, and while it gets the program to work, I'm also looking for why, suddenly, Xcode was okay before, but now wants the entire file path. — NonCreature0714, Dec 05 '15 at 13:13
I think maybe the problem is outside xcode, a search path missing? — AndersK, Dec 05 '15 at 14:19

Short answer is, my project was broken because it was trying to run a project in a path where a previous project already existed. Once I deleted both completely, and started anew, my program worked just fine.

While I made no changes to the original project, I started a new project in the same directory, which then caused all my issues.
