file manipulation

i'm having problems with the edit function on my program. when i enter something, it crashes. it prints out "File not found" endlessly.

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

void info()
{    
     cout << "               **********************************************" << endl;
     cout << "               *                 Case Study - 2             *" << endl;
     cout << "               *                   Phonebook                *" << endl;
     cout << "               *                   Y - 201                  *" << endl;
     cout << "               *                                            *" << endl;
     cout << "               *                                            *" << endl;
     cout << "               *                                            *" << endl;
     cout << "               *                                            *" << endl;
     cout << "               **********************************************" << endl;
}
