        while read -r line;   #reading lines in the while loop
        do
        for word in $line;  #for loop to count words in a line
        do
        read -ra ARR <<< "$word"   #will read $word to an array named ARR
        for i in "${ARR[@]}"; do # access each element  of array
        echo "$i"             #to see what are the elements of array
        count=$((count+1))  #keeps the count of the words seperated.
        done
        done
        done <$input
        echo "c= $count "   #displays the final
