I have successfully created a zip code radius search, but the performance is
unacceptable.
I have two tables. The first is 52K zip codes w/lat and long. The second is
3K national business addresses.
Using the zip code 10010, it takes almost 60 seconds to return 122
businesses within a 25 mile radius. This slowdown is almost entirely due...

24.1.1.3 says about InputIterators:
Algorithms on input iterators should never attempt to pass through the
same iterator twice. They should be single pass algorithms.
In 24.3.4.4 summarizes the effects of std::distance as:
Effects: Returns the number of increments or decrements needed to get
from first to last.
The wording of the latter...

As an intellectual exercise, I've implemented an STL-esque List<and
List<>::Iterator. Now, I would like a signed distance between two
iterators which corresponds to their relative position in the list.
For instance, if I did something like distance(list.end(),
list.begin()), I would get -list.size(). The STL's iterator distance
function...

1. The following code snippet uses minus operation on two pointers to
calculate the distance between struct members. This is illegal, right?
2. s1 and s2 are type of the same struct S. Can the distance of s1.i4
between i3 be used to deduce the distance between s2.i4 and s2.i3?
Thank you for your time.

I'm a little lost on my program. Everything works fine except function 3. It gives out garbage numbers. Its suppose to give the distance between two points and then the area of 2 circles.

#include <string>

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it. ...
