structure assignment vs memcpy

[subramanian100in]

Suppose I need to assign one structure to another.
Should each member of the structure be assigned individually or can
memcpy be used ?

Since the compiler can add padding bytes, which approach is always
safer ?

Simply assign one object to another with the assignment operator.
Structure assignments have been supported since C90.

Of course if you only want to assign some members of a struct object
to another, then you'll have to do it manually.

Using memcpy is not usually necessary, since the language directly
supports copying structures.

There seems to be a whole bunch of you doing the same course, asking
the same questions over and over again. Why don't you get together and
nominate one of you to do all the homework?
