fstring not reading from .txt file - c++

Question

I am trying to write a program that will read a .txt file that is called when the program is run from terminal.
the command used will be;
$ ./myexecutable input.txt
My program and the input.txt are in the same directory. My code so far is as follows
#include <string>
#include <fstream>
using namespace std;
int main(int argc , char* argv[]){
string temp = "here";
string filename = argv[1];
ifstream myFile (filename);
myFile.open(filename);
if (myFile.is_open()){
while (getline (myFile, temp)){
cout << temp << endl;
myFile.close();
}
} else {
cout <<< "You have Entered Wrong File Name" << endl;
}
cout << "do with the simple program" << endl;
return 1;
};
but the output I get is just
file opened, do with the simple program
I am not really familiar with fstream so don't know where I may have gone wrong. I followed their tutorial found here.
but clearly I've done something wrong.
Thanks for your help.

This is the corrected code!!
You were opening myFile twice!!
First time in this statement ifstream myFile (filename);
Second time in this statement-myFile.open(filename);
#include <string>
#include <fstream>
#include <iostream>
using namespace std;
int main(int argc , char* argv[]){
string temp = "here";
string filename = argv[1];
ifstream myFile (filename);
if (myFile.is_open()){
while (getline (myFile, temp)){
cout << temp << endl;
myFile.close();
}
} else {
cout << "You have Entered Wrong File Name" << endl;
}
cout << "do with the simple program" << endl;
return 1;
};
