Here we demonstrate how can we show the star (*)
for an input password. It may be used when we are developing an application
that has a login form in which we use a user name and password as logging
information.
For security purpose it is needed to show (*) instead showing the
plain text for the password. The source code is given below to show how we can
do it using c/c++.
Source Code:
#include <stdio.h>
#include <conio.h>
int main()
{
char password[20], ch = 0;
int i = 0, j;
printf("Enter the password
<limit 20 characters>: ");
while (i < 20)
{
ch
= _getch();
if (ch == `\r`)
break;
password[i]
= ch;
i++;
ch
= `*`;
printf("%c", ch);
}
password[i]
= `\0`;
printf("\nThe password is
:");
for (j = 0; j < i; j++)
{
printf("%c", password[j]);
}
_getch();
return 0;
}
Output:
