Well, A simple solution would be to read in all the data. Find the person whose data needs to be edited. Then after that. Edit the data.
Then Write the file all over again .

void editAppointmenRecords( )
{
	int editname;
	system("cls");  //clear screen
	cout<<"\nEnter person Name you want to Edit: ";
	cin>>editname;
	ifstream edfile("C:\\AppointmenRecords.txt");
	if(!edfile)          //return true if file is not opened
	  {  cout<<"\nFailed to open file!!!!\n";       //indicate program failed
		 cin.get();           
            readAppointmenRecords( );
for (for (int a=0; index<currentSize; a++)
{
if(editname==AppointmenList[a].name)
{
//Provide Edit Options here
}
break;
}
void writeAppointmenRecords( );

}
	  }

}

I guess something like that.
