CLion C++ can't read/open .txt file in project directory

Question

I have a .txt file in my project directory that I made and populated with data.

directory structure looks like:

/Users/asd/ClionProjects/ProjectWithTemplates/
main.cpp
cmake
twoday.txt

here is my code:

#include <iostream>
#include <array>
#include <cmath>
#include <fstream>


using namespace std;

/* print array prototype */
template <size_t N>
void printArray(const array<double , N> & arr);

/* mean function prototype */
template <size_t N>
double meanArray(const array<double , N> & arr);

/* standard deviation prototype */
template <size_t N>
double sDeviation(const array<double , N> & arr);

int main() {

    string date1;
    string date2;

    array<double, 24> day1Temps;
    array<double, 24> day2Temps;
    array<double, 3> testarr = {75,70,65};

/* TESTING PURPOSES */
    printArray(testarr);
    sDeviation(testarr);
    cout << "standard deviation of array is: " << sDeviation(testarr) << endl;
    cout << "mean of array is: " << meanArray(testarr) << endl;
/* END TESTING */

    ifstream inputFile;
    inputFile.open("twoday.txt");

    if(inputFile.is_open())
    {
        inputFile >> date1;
        inputFile >> date2;

        for(int i = 1; i < day1Temps.size(); ++i)
        {
            inputFile >> day1Temps[i];
        }

        for (int j = 1; j < day2Temps.size(); ++j) {
            inputFile >> day2Temps[j];
        }
    } else cout << "File unable to open. File does not exist." << endl;


    return 0;
}

/* print array defination */
template <size_t N>
void printArray(const array<double , N> & arr){

    for(const auto & i : arr)
    {
        cout << i << " ";
    }
    cout << endl;
}

/* mean function defination */
template <size_t N>
double meanArray(const array<double , N> & arr){

    double sum;

    for (const auto & i : arr) {
        sum+=i;
    }

    return sum/arr.size();
}

/* standard deviation defination */
template <size_t N>
double sDeviation(const array<double , N> & arr){

    double mean = meanArray(arr);
    double total;

    for (const auto & i : arr){
        total+=pow(i - mean, 2);
    }
    return sqrt(total/arr.size());
}

Eveything else works fine besides my file IO. Very strange.

adding some details..............more details? :(

Clion looks for input files and writes output files to the Debug folder. If you put your input files in there it will see them.
