can anybody explain complete execution of cout statement ?

[Anshh]

cout<<"Hello world";

how this gets executed.what is cout and << and what these do ?

[MiiNiPaa]

std::cout is an standard C output device: usually the console.
<< is an operator. You can see your line as a function operator<<(cout, "Hello world");
It sends the "Hello world" string to standard output.
