What is "far" and "near" pointers in "c"...?

Answer Posted / narasimha

"near" and "far" pointers are actually non-standard
qualifiers that you'll find only on x86 systems. They
reflect the odd segmentation architecture of Intel
processors. In short, a near pointer is an offset only,
which refers to an address in a known segment. A far pointer
is a compound value, containing both a segment number and an
offset into that segment.

Segmentation still exists on Intel processors, but it is not
used in any of the mainstream 32-bit operating systems
developed for them, so you'll generally only find the "near"
and "far" keywords in source code developed for Windows 3.x,
MS-DOS, Xenix/80286, etc.

In a gymnastic competition, scoring is based on the average of all scores given by the judges excluding the maximum and minimum scores. Let the user input the number of judges, after that, input the scores from the judges. Output the average score. Note: In case, more than two judges give the same score and it happens that score is the maximum or minimum then just eliminate two scores. For example, if the number of judges is 5 and all of them give 10 points each. Then the maximum and minimum score is 10. So the computation would be 10+10+10, this time. The output should be 10 because 30/3 is 10.
