Question

I am unable to figure out why my code is not able to open and read a file. What am i missing?

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main (int argc, char * const argv[]) 
{
    string line;
    ifstream myfile ("input_file_1.txt");
    if (myfile.is_open())
    {
        while (!myfile.eof())
        {
            getline (myfile,line);
            cout << line << endl;
        }
    }
    else
    {
        cout << "Was unable to open the file" << endl;
    }

    return 0;
}

The file “input_file_1.txt” is int he same directory as my .cpp file and it has read permissions. I even gave gave it 777 permissions and i was unable to read it.

Can anyone tell me what i am doing wrong? I really cannot figure it out….

Answer 1

• Try to use full path for the file
• The default location to look for the file is where the executable is , not where the source is.
