prints out the marks for that name..how do i do it???something like
getting a value for a key..but from a keyboard input.

So do you know how to do it when the key does not come from a keyboard?
What have you tried? In what way does it fail? Show your work.

You break down the problem into smaller pieces:
- first you read the input from the keyboard
- then you retrieve the associated value from the hash
- then you print it
(the second and third step can easily be combined)
Which part do you have problems with?

Show us some code and we can probably pinpoint why it doesn't work.
