if [ "$#" -eq 0 ]; then
  array=( defaultarg1 defaultarg2 )
else
  array=( "$@" )
fi

# changing the order of elements
array=( ${array[3]} ${array[0]} ${array[2]} ${array[1]} )

# taking another array
strings=( "first" "second" "third" "fourth")

# lenght of array
len=${#array[@]}

# printing all elements
for (( i=0; i<$len; i++ )); 
do 
        echo "The ${strings[$i]} array value is \"${array[$i]}\"" ; done
