Many of us keep want this ultimate solution, “that how can we add provide a password facility in a c++ or c program?”. Yes password facility such that if user enter “UltimatePedia” as his password then it should be displayed over the screen something like-”*************”. So here i give you the solution of this query (asked to me by many of you through mails):-

 

 #include<iostream.h>  //Header file for cout and cin.

#include<conio.h> //Header file for clrscr().

void main()

{ clrscr();  //To clear off the screen.

   char psw[20];  //Size of the password.

   char psw2=13;  //Basically here 13 is the ASCII value for the “Enter”.

   int i=-1;

   cout<<”Enter your Password:”;

   do{ i++;

   psw[i]=getch();

   cout<<”*”;  //Displays “*” instead of the characters entered by the user.

   }while(psw[i]!=psw2);  //This loop runs untill user press enter or character limit for password is reached.

cout<<”ntPassword is accepted. Your password is:”<<psw;  //Optional facility which displays the password as entered by the user. Note that it does not show the password in the “*”  form.

getch();  //Termination of the program.

}

 

Now do i hope you can modify this program according to your need in a program. And if you still have any queries related to its working then do ask me.
