Obvio it will be compilation error , you are using undeclared a

Assuming a is declared first.

  • In a system that uses little-endian (Like  Intel x86 processors ) the answer should be $513$
  • In a system that uses big-endian (Like IBM z/Architecture mainframes ) the answer should be a very large value.

 Answer should be (a) Machine dependent

debashish,how do u know that it is endian notation??
and if  'a' is a int variable then how will x[0] and x[1] work??

i mean a is an integer type variable,so what will be x[0] or x[1] refer to??


A prerequisite to know what is happening

thanks @kapil..
