Fixed bug where wc was taken from words instead than lines

q4/q4.sh

-#!/bin/sh
+#!/bin/bash
 # wc generated_output.txt |awk '{print $2}'
 
 
 mismatch=$(diff generated_output.txt actual_output.txt | grep "c" | wc -l)
-total=$(wc actual_output.txt |awk '{print $2}')
-score=$(echo $total-$mismatch | bc)
+total=$(wc -l < actual_output.txt)
+score=$((total-mismatch))
 echo "Secured $score marks out of $total"
