How do we get the entry point for the program execution ? [ Example : main() in the C program ] Script based. There is no particular entry point. 3. How does dynamic memory handled ? Is it supported in first place ? Instances for the classes can be created. Automatic Reference counting mechanism has the strong reference to one of the variable. Till there is strong reference to the variable it'll be there in the memory. Once there is no strong reference it'll be de-initialized.

Procedure to enable wireless LAN adapter in vmware!

I have went to find the way in which wlan in Kali Linux could be made listed my airmon-ng command. Most of the videos and posts suggested me that it is necessary to have another wi-fi adapter to have connected to wifi network. But this is not necessary. The procedure to do this is as follows: 1. Download this package in Virtual Machine(Kali linux) " http://wireless.kernel.org/download/compat-wireless-2.6/compat-wireless-2010-06-26-p.tar.bz2" 2.Unzip this package in terminal i.e navigate to place where you have downloaded this file , say desktop then type : cd Desktop for unzip type : tar -jxvf compat-wireless-2010-06-26-p.tar.bz2 3. Navigate into the uncompressed directory and type: i."make unload"  (only words within the quotes are the commands) ii."make load" Done!  now airmon-ng  should have the list of the required devices.
