Chatting via cmd(useful in practical exam)

Dedicated to all my frnds during practical exam

I personally feel that cheating is necessary during practical exam.....but if we do cheating in traditional manner it will definitely cause problem for us....so here is the method of cheating:

step1 :All you need is your friend's IP Address and your Command Prompt.
as we know that during practical we are connected via LAN....we need only ip address of our computer on which we r sitting..
so here is the command for finding the ip address
open cmd & type ipconfig on cmd
default gateway==127.0.0..... will appear on cmd thats ur ip address

step2. Open Notepad and write this code as it is.....!
@echo off
:A
Cls
echo MESSENGER
set /p n=User:
set /p m=Message:
net send %n% %m%
Pause
Goto A

step3. Now save this as "Messenger.Bat".
