I do this in this way but secound part (create onother file and copy first file ino it ) is not working

I am a bigginer in programming please help me !!!

#include<iostream>
#include<conio.h>
#include<fstream>
#include<iostream>

using namespace std;

int main()
{
	ofstream out("D:\\test.txt");
	if( out.fail( ) )
	{
		cerr<< " can not open the file ";
	
		_getch();
		return 1;
	}
	out<<123<<" "<<123.23<<endl;
	out<<"This is a text file . ";
	out.close();
	

	fstream in("D:\\test.txt");

	}

	ofstream output ("E:\\test file.txt");
	output.open("E:\\test file.txt");
	if(output.fail( ))
	{
		cerr<<"Unable to create a file";
		getch();
		return 1;
	}

	while( !in.eof( ) )

	output.close();
	in.close();

	_getch();
	return 0;
}

output of this code is : No such file a Exist

Does the file exist? If it does, you only need to open it once.

fstream in("D:\\test.txt"); opens it.

thanks
yes this is exist

but problem is here (I solved myself ;-) :

ofstream output ("E:\\test file.txt");
	output.open("E:\\test file.txt");

that should change to :

ofstream output ;
output.open("E:\\test file.txt");

and same way ,

fstream in("D:\\test.txt");
in.open("D:\\test.txt");

should be

fstream in;
in.open("D:\\test.txt");
