Answer Posted / ram
actually pragma pack is used for structure padding
we are having #pragma pack 0,#pragma pack 1,#pragma pack
2,#pragma pack 3,#pragma pack 4
in this first one will allocate memory 4 bytes for every
data type
in second one i.e in pack 1 it allocates 1 byte for every
data type
in third one i.e in pack 2 it allocates 2 bytes for every
data type
in fourth one i.e pack 3 it allocates 3 bytes for every data
type
in fifth one i.e pack 4 it allocates 4 bytes for every data type
Actually pragma will be used in powers of 2 only
