Im trying to read the contents of a file in C++, but when I go to run the program it keeps failing. Not sure if this is because I’m using ubuntu linux.

Image of my code i used
Seems basic enough but for some reason the file never opens and continues to fail

  // This program reads data from a file.
#include <iostream>
#include <fstream>
using namespace std;

int main()
{
   // Create a text string, which is used to output the text file
string myText;

// Read from the text file
ifstream MyReadFile;
MyReadFile.open("nums");

if(!MyReadFile){
  cout << "Failed" << endl;
}
else 

// Use a while loop together with the getline() function to read the file line by line
  while (getline (MyReadFile, myText)) {
  // Output the text from the file
    cout << myText;
  }

// Close the file
MyReadFile.close(); 
}
