You just accept keyboard input but don't display it. You would use getch for this, which is in conio.h.

I am at a loss. You're learning C, but you don't understand my answer and can't use google ?

char c,password[10];
int i;
while( (c=getch())!= '\n');{
password[i] = c;
printf("*");
i++;
}

First i should say i write in Linux,
and in Linux there isn't any conio.h.
and it is better i say i want to use this in a honeypot. when server send a prompt for client and client want to type password nothing display.

Christian's code snippet is the answer to your question when changing the function call and the include file for Linux: Use getchar() defined in stdio.h.

Christian Graus 4-Aug-12 4:33am

Ah, it seems in Linux there;s

#include <unistd.h>
char *getpass(const char *prompt);
