#include <iostream>
#include <fstream>
#include <cmath>
#include <cstdlib>
using namespace std;

int main (){
    char filename [50];
    ifstream asd;
    cin.getline (filename, 50);
    asd.open(filename);
    
    //to close the program if txt does not open
    if (!asd.is_open()){
                        exit(EXIT_FAILURE);
                        }
                        
    char word [50];
    asd >> word;
    while(asd.good()){
                      cout << word << " ";
                      asd >> word;
                      }
                      
    system ("pause");
    return 0;
}

program runs but i can't create txt files

If you're trying to create a file, I presume you mean an output file.
I don't see any output file in your program.

The program doesn't create text files, it reads them and displays the content.

Then I don't understand your problem. In your OP you state "i can't create txt files".

I think you mistook my answer for the OP's reply ;-)

Thanks,
where do i need to put the name of the file to be read ?

[jim80y]

Now I'm confused.

What you have posted is a fully working program that reads a filename from the user and then opens that file and displays the content. I note that it doesn't prompt for the filename, it just immediately reads the input, so that may be confusing you when you run it - it may seem like it's not doing anything.

But is that what you expect the program to do? If it is, and it's not doing that, can you tell us exactly what the problem is?

If that's not what you expect it to do, what do you think it should be doing?

Cheers,
Jim

Alright, i finally understood it.
I need to write the file to read on screen.
Thanks for your help.
