Even this will not be true always. Because of the memory alignment, eventually size of a structure would be >= the sum of sizes of individual structure members.

There is concept called as "Padding" which is completely Operating system dependend.ex:struct a{ int a; int b; char c; int d;}Answer : 2 + 2 + 1 + 2 (bytes) = 7Bytes (not correct always) can be 8bytes since the allocation is done in "word" size which is 2bytes [generally -> depends on O/s and processor]
