Question

Is is possible to implement the password field which we see on webpages using C language???

Answer 1

This code can serve the purpose:-

#include <stdio.h>
#include <conio.h>

#define MAX 25
#define passfield 1

void main()
{
 char password[MAX], passchar;
 int i=0;
 clrscr();
 printf("Enter password: ");
 while(passfield)
 {
  passchar=getch();
  if(passchar==13)
   break; // 13 is the ASCII value of ENTER
  if(passchar==8) // 8 is the ASCII value of BACKSPACE
  {
   putch('\b');
   putch(NULL);
   putch('\b');
   --i;
   continue;
  }
  password[i++]=passchar; //else store characters in password
  passchar='*'; //mask password character
  putch(passchar);
 }
 password[i]='\0'; //end of the char array
 printf("\n%s",password);
 getch();
}
