What would be the result...

[Sreeramu]

Hi friends at present i am not having any compiler so please can any one conform the result of this program
what would be the size of this structure

struct str 
{ 
int data; 
struct str *pstr; 
chap ch; 
int data1; 
};

what would be the size of this structure...

In VS 2005 the size is 16, but i believe this is system/compiler dependent so there could be different answers.

We don't know because we don't know the size of ints and chars on your system,
nor do we know the size of pointers nor the alignment requirements of your system.

kind regards,

we don't know the size of <snip> chars on your system

In fairness since the size of everything is measured in units of char the size of char will not effect the size of a structure (or anything else) only the min/max values of the integers on the system and I fuess possibly the representation of floats and doubles.

16 is correct for int it would take 4 bytes and for char 4 bytes(due to structure padding) and the pointer 4 bytes so 4+4+4+4=16 ....

You need to read post 3 much more carefully and understand what it is saying, I have worked/do work on a system where the correct answer is 7 and another where the answer is 8.
