C Program : Password Input Problem

  1. while((c=getch())!=13)
  2. {
  3. pass[z++]=c;
  4. printf("%c",'*');
  5. }
I used this while loop to take the input of the password. Everything works fine until no "wrong" key is pressed.
the problem is, suppose, if i press a wrong key n i want to delete it (backspace) then even backspace is taken as a character.. How to rectify the code??

    Apply condition : If backspace then decrement the counter and continue
    For screen move a step back and replace * with ' '

    😎. Specify if any other doubt 😀

    yeah i've did it this way before but the thing is, using a whitespace disturbs the password and even the buffer memory is getting wasted in this way..
    I got it now 😀 that too in more efficient way.. using fflush() and fputs()
