PowerShell, creating statistics

# Creating statistics in PowerShell is very easy. There is no need to
# create several variables, it can all be combined into one!

# This is how it can be done


# Create hash-table a.k.a. associative array
# Note that you do not have to define the members before using them
$stats=@{}

# do something, here the distribution of random numbers are
# used as an example, but in the real world it could be the
# number of objects processed, number of updates succeeded
# and number of failed operations

$random=new-object system.random

1..1000 | % {
 $n=$random.next(0,10)
 switch ($n) {
 # Increase the counters
 0 { $stats.zeroes+=1; break }
 1 { $stats.ones+=1; break }
 2 { $stats.twos+=1; break }
 default { $stats.others+=1 }
 }
}

# report the results
$stats

# Output
Name                           Value
----                           -----
twos                           93
zeroes                         108
ones                           104
others                         695


# this is almost too easy...

# Hint: If you want pretty-formatted names, use $stats."Pretty Name"+=1
