Maybe you could have an adjustment value that you would always add. When the counter gets high, you set the adjustment value to -1. When it gets back to zero, you set it to 1. That way, you only have one function plus a decision to make about if you need to change the adjustment value:-
Then, a simple loop will illustrate it:-

Hello,
Please tell me if there is a better way to get the number of elements from an array that is passed to a function.
This is what works on Solaris 8 (ksh) but it looks odd:

b2='}'

Please excuse my ineptitude for a bit as I've been spoiled for the past few months with only writing perl code instead of C.
So ok, I've been thinking about some code to change the crc32 values that are held within central directory headers of zip files.
Because I'm lazy I decided to just... (3 Replies)

I have a question on how can I assign a output of a function to a variable which is executed in background.
Here is my example

I have the following code to count the number of how many times the name occurred in one file. The code is working fine and the output is exactly what I want.

MEMSHUFFLE(3pub) C Programmer's Manual MEMSHUFFLE(3pub)NAME
memshuffle - make an array be in random order
SYNOPSIS
#include <publib.h>
void *memshuffle(void *block, size_t elsize, size_t elnum);
DESCRIPTION
memshuffle will move around the elements of an array in a random fashion. It uses the standard library function rand(3) to get the pseudo-
random numbers it needs. The caller must set a suitable seed with srand(3).
RETURN VALUE
memshuffle returns its first argument.
EXAMPLE
To shuffle an integer array one might do the following.
int array[4] = { 1, 2, 3, 4 };
memshuffle(array, sizeof(array[0]), 4);
BUGS
On many systems rand(3) is not of very good quality. However, it is the only random number generator that can be assumed to exist. Making
it possible for the caller to provide an alternate source of random numbers (e.g., via a function pointer) is perhaps too more trouble than
its worth. A better way would be for everyone to fix their rand's.
