Sure, I suppose... I guess I'm not seeing the point. If you can't do sizeof() on something, you can't measure it with pointer tricks either. Nothing's gained, and legibility is lost.

we know that sizeof never returns zero when used with structure
then why in this case it is returning zero
struct foo
{
char c;
};
void main()
{
struct foo f;
cout<<sizeof(f);
}

I am trying to find out ways of comparing a value from a 'c' structure to a value in another 'C' structure. the 'C' structure can be a List or liked list as it contains lot many records.
if we loop it in both the structures it is going to consume time.

Hi,
There are some bewildering sizeof() questions I have in my mind. Could anyone shed some light on this?
int main() {
printf("%d\n", sizeof(main)); // Ans: 1
}
That is, the sizeof() a function identifier though it is treated internally as a pointer gives 1 byte always, why?

elf64_fsize
elf32_fsize(3ELF) ELF Library Functions elf32_fsize(3ELF)
NAME
elf32_fsize, elf64_fsize - return the size of an object file type
SYNOPSIS
cc [ flag ... ] file ... -lelf [ library ... ]
#include <libelf.h>
size_t elf32_fsize(Elf_Type type, size_t count, unsigned ver);
size_t elf64_fsize(Elf_Type type, size_t count, unsigned ver);
DESCRIPTION
elf32_fsize() gives the size in bytes of the 32-bit file representation of count data objects with the given type. The library uses version
ver to calculate the size. See elf(3ELF) and elf_version(3ELF).
Constant values are available for the sizes of fundamental types:
Elf_Type File Size Memory Size
ELF_T_ADDR ELF32_FSZ_ADDR sizeof(Elf32_Addr)
ELF_T_BYTE 1 sizeof(unsigned char)
ELF_T_HALF ELF32_FSZ_HALF sizeof(Elf32_Half)
ELT_T_OFF ELF32_FSZ_OFF sizeof(Elf32_Off)
ELF_T_SWORD ELF32_FSZ_SWORD sizeof(Elf32_Sword)
ELF_T_WORD ELF32_FSZ_WORD sizeof(Elf32_Word)
elf32_fsize() returns 0 if the value of type or ver is unknown. See elf32_xlatetof(3ELF) for a list of the type values.
For the 64-bit class, replace 32 with 64 as appropriate.
