Can somebody tell me how to make cold or hot coffee like café or suggest me any book that is available on net as freeware

Buy flavored coffee... use syrups.

To make a pot of coffee: You'll need a coffee pot. Put a tablespoon of coffee grounds in a filter for each cup of coffee that you want. For example - if you want 4 cups of coffee, put in 4 tablespoons of grounds. Pour water into the filter, and push the button :) (I like it strong, so you can use less coffee)

If you want cold/iced coffee, make a pot of extra strong coffee and serve over ice.

If you want a "capuccino" like in a café, fill your cup 3/4 with coffee, 1/4 with milk or cream, and then top with whipped cream and a sprinkle of cinnamon. :) it makes a nice treat.

Did you mean the kind of coffee you would get in an american coffee house, french style café, or italian style espresso?

To make real french coffee, you'll need a little contraption called a french press.

Here you can find a picture on it, as well as information on how it works:

French press - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/French_press)

To make italian style coffee, meaning espresso, you'll need an espresso pot.

Here are some great links on the subject:

Moka Express - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Moka_Express)
French press - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/French_press)

In any case, make sure you get the right grind for the kind of coffee you're making.
