now that I have this 2 dimensional array I would like to do this afterward:
I want to fill an empty matrix with these letters in this array. The reason for creating random numbers is to take the letters in a random order.
So I add another column to this array with 0 values:
print "$TF[$i]\t" . rand(1) . "\t0\n";
After sorting based on random numbers the letter is taken and feed to this empty matrix. Each row shouldn't have more than 3 letters in total. by taking each letter the 0 value in array is replaced by 1 , so next time if it is 1 means that we have to skip since it has been taken once.
I am trying to reference a two dimensional array in a
subroutine and can't seem to figure this one out in Perl.
Does anybody know? Please enlighten me.

Hello, all
For a 1-dimensional array, such as
myarr_1=1
myarr_1=2
myarr_1=3I know I can write a loop as below to show the array member one by one:
for (i in myarr_1){print i, myarr_1}Now, suppose I have a two dimensional array such as:
myarray_2=1 myarray_2=2
myarray_2=10 myarray_2=20My... (3 Replies)
I have an array of names. Each one of the name, has a number represented to it.
For example A has an ID 8, B has an ID 2.

declare -a arr=("A" "B" "C"... (6 Replies)

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.
