int main ()

exit(1) ;

}

while(!out.eof())

هذا هو البرنامج

هل هذا يفي بالغرض :

#include 
#include 
#include 
#include 

int main ()
{
	ScreenClear ();
	fstream out ;
	int x ;

	out.open("a:/zoo.txt",ios::in | ios::out);
	if (out.fail())
	{
		cerr<<"can not open the file " ;
		exit(1) ;
	}
	while(!out.eof())
	{
		out >>x;

		out <<"n ok ";
	}
	out.close();
	return 0 ;
}
