C++ Password character echo
The problem statement, all variables and given/known data
Currently using stdio.h, conio.h, string.h, stdlib.h
not using iostream, namespace std etc.
I am asked to make a password prompt where each character echoes an asterisk (*)
The user must be able to backspace and delete to make corrections.
The password is then stored in an array which can accomodate up to 100 passwords.
The attempt at a solution
while(c != eof())
if (c != eof())
pw[userid][count] = '\0';
sadly, the output indentation looks horrible and it is uneditable using backspace and delete.

As I recall, getch returns any key presses. This includes control characters, such as, say, the backspace character (ASCII 0x08):
You might also want to do some input filtering to ensure that only characters you want accepted actually are (again, look at the ASCII table). Lastly, rather than go crazy with allowing the user to edit and change the password, you might want to consider using a "Please type password again", just to make sure the user is entering both the same.
