Any additions for write-to-file short program

[pascal111]

In next program that rewrites original written texts into new 
files, I see that it may need some additions or we can accept it 
like this because it's just a simple program that achieve its 
task and doesn't need any philosophical additions.

Example:

Original text:

Learning C doesn't impact bad on C++. In theoretical speaking we 
think that C++ is C with some new features, but these features 
maybe tends to some high level, and working with C is more 
difficult than direct learning of C++, because last one provides 
features or tools make us pass some low level ways we have to use 
in C to do same tasks, so, the work with C impact good on 
learning C++ because we see everything with its real nature in C.

New produced text in new file:

Learning C doesn't impact bad on C++. In theoretical speaking we 
think that C++ is C with some new features, but these features 
maybe tends to some high level, and working with C is more 
difficult than direct learning of C++, because last one provides 
features or tools make us pass some low level ways we have to use 
in C to do same tasks, so, the work with C impact good on 
learning C++ because we see everything with its real nature in C.




Code:

// D programming language

import std.stdio;
import std.string;

int main()
{

string s;
char[] f;


try{
write("Enter file name and path: ");
readln(f);
f=strip(f);}

catch(Exception err){
stderr.writefln!"Warning! %s"(err.msg);}


     File file = File(f, "r");
     File file2 = File("output_x.txt", "w");

     while (!file.eof()) {
           s = chomp(file.readln());
           file2.writeln(s);
        }

     file.close();
     file2.close();

return 0;

}
