C++ code for password entry

[tcsvikr]

Hi,
I'm a newbie in c++...Can anyone provide me with the C++ code for entering the password...It should be in this way..
The user enters the password but only *'s should be displayed...Ass ume that there is a flat file which contains the details of users and their respective passwords. Authentication should be provided after checking the file...

Its urgent..Thanks in advance...

Hi Vijay,

Welcome to TSDN. What have you done so far? We cannot provide you direct code as per posting guidelines. Kindly post your perticular problem and paste your efforts in code tags so that we can help you.

Google is a friend always!

[code=c]#include<stdio. h>
#include<conio. h>
int main()
{
char ch;
char pass[20];
int i=0;
while((ch=getch ())!=13 && i < 20) //13 is ascii value for "Enter" key, I am not sure.
{
printf("*");
pass[i++]=ch;
}
//here pass will contain your password.
}
[/code]
This code will work if you have conio.h file.
On posix platform probably you need to download "kbhit" and use kbhit instead of getch in above code.

A note on the above - using conio.h means that you are using a non standard header and this will not work on all machines. If you are going to deploy this to a mass number of machines, I would recommend thorough testing to make sure they are all compatible, or finding another method of implementation.
