Bitcoin address? – Bitcoin battery exchange

I use the following sites for free bitcoins;



They are not worth much but just for fun; – /

I've visited a website that claims to give me 7-1200 Satoshi free every hour. But that's asking me a Bitcoin address. From where I can get this address. Do I have to pay an amount to get this address?

Although I am absolute beginner on this site, so if I have asked for something wrong, let me know in the comment so that I can delete my question!
