Bash script to find comments in file

As I stated in a previous thread - I'm a newbie to Unix/Linux and programming. I'm trying to learn the basics on my own using a couple books and the exercises provided inside.

I've reached an exercise that has me stumped. I need to write a bash script that will will read in a file and print the line number and script line of all lines including comments. Normally this wouldn't be difficult, but I'm not supposed to use sed, awk, grep, etc (only Bash). I have the skeleton in place, but I'm missing how to pull only the comments and display the line number. Any help would be appreciated.

Code:
#!bin/bash

while read line
do
echo $line
done
