Hi Mahmmadullah,

It sounds like you're asking for help with homework. I suspect there will be general reluctance to help you with that in more than general terms, and also reluctance to provide a personal contact address. Why don't you try asking the list directly, without including actual scans? 

To have the best chance of getting answers, your questions should:

- Be clear and simple
- Be general. Avoid "what is the result of this expression" questions.
- Include details about what you've already tried and any error messages you got.

Some examples:

Bad: "Here is a specification. Please give me code."

Probable answer: Total silence.


Better: "I'm building a simple webserver and having trouble with HTML parsing. I can't figure out how to handle attributes. Any suggestions?"

Probable answer: "Take a look at the html-parsing package or one of the equivalents. Alternatively, if you are required to write it yourself, try accumulating them together using 'for/hash'."


Best: "I'm building a simple webserver and when I try to connect it throws exn: network:foo and spits out the following error stack. I think the issue is in the chunk of code I've included below, but I have no idea what it might be in particular. Help?"

Probable answer: "You didn't <thing> and here is some code to fix it. Also, you could simplify things like this <code>. Don't forget about <other thing>; you can find more in <link to relevant documentation>."
