You seriously don't need to worry about overhead of an extra line of code.
Lets do some rough guess calculation here...
What you got a 2GHZ processor? That's 2000,000,000 cycles per second.
Lets say that extra line adds 20 cycles on the program. That's a 10 millionth of a second.
Reading a few bytes from a disk may well take in the order of milliseconds.
If you think it makes the program clearer then do it. I routinely add extra steps and variables to make my code more readable and I deal with vast amounts of 24 hour streaming data.
And my stuff flies.
Its I/O that causes bottlenecks.

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);

Hi All,
is it possible to find out the size of an array of structures ( without using 'sizeof' operator). The condition is we have the array of structure instant but we are not aware of the elements inside the structure.
Can someone help me out?
Thanks in advance. (18 Replies)

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?

cfdisk
CFDISK(8) GNU cfdisk Manual CFDISK(8)
NAME
GNU cfdisk - a curses-based partition table manipulation program
SYNOPSIS
cfdisk [options] [device]
DESCRIPTION
cfdisk is a disk partition manipulation program, which allows you to create, destroy, resize, move and copy partitions on a hard drive
using a simple menu-driven interface. It is useful for organising the disk space on a new drive, reorganising an old drive, creating space
for new operating systems, and copying data to new hard disks. For a list of the supported partition types, see the --list-partition-types
option below.
OPTIONS
-h, --help
displays a help message.
-v, --version
displays the program's version.
-a, --arrow-cursor
use an arrow cursor, instead of reverse video highlighting, in case your terminal doesn't support it.
-z, --new-table
create a new partition table on the disk. This is useful if you want to change the partition table type or want to repartition you
entire drive. Note that this does not delete the old table on the disk until you commit the changes.
-u, --units=UNIT
sets the default display units to UNIT. A list of possible units is given below.
-t, --list-partition-types
displays a list of supported partition types and features.
UNITS
You can choose in what unit cfdisk should display quantities like partition sizes. You can choose from sectors, percents, bytes, kilobytes,
etc. Note that one kilobyte is equal to 1,000 bytes, as this is consistent with the SI prefixes and is used by hard disk manufacturers. If
you prefer to see the sizes in units with binary prefixes, you should instead select one kilo binary byte (kibibyte), which is equal to
1,024 bytes. Whatever display unit you have chosen, you can always enter the quantities in the unit of your choice, for example 1000000B or
1000kB.
compact
display each size in the most suitable unit from B, kB, MB, GB and TB.
B one byte
kB one kilobyte (1,000 bytes)
MB one megabyte (1,000,000 bytes)
GB one gigabyte (1,000,000,000 bytes)
TB one terabyte (1,000,000,000,000 bytes)
KiB one kilo binary byte (1,024 bytes)
MiB one mega binary byte (1,048,576 bytes)
GiB one giga binary byte (1,073,741,824 bytes)
TiB one tera binary byte (1,099,511,627,776 bytes)
s one sector. It depends on the sector size of the disk. You can use it if you want to see or choose the exact size in sectors.
% one percent from the size of the disk
cyl one cylinder. It depends on the cylinder size.
chs use CHS display units.
BUGS
There are no known bugs. We are in early stages for development, so be careful.
