Answer / karthikeyan

union is unified memory where structure is non unified memory.

all members of structure occupy consecutive chunks of
memory.but union members will share the most highest memory
of the union member.i.e data type.

we can access all the members of structure at a time.

but in union we can access a single union member at a time.

Answer / sevak.yatrik777

While structure enables us treat a number of different
variables stored at different in memory , a union enables us
to treat the same space in memory as a number of different
variables. That is a Union offers a way for a section of
memory to be treated as a variable of one type on one
occasion and as a different variable of a different type on
another occasion.
