How can I get a contract address?

Excuse me, I'm a bit confused about how to acquire a contract address. Could you please elaborate on the steps I need to take to get one? Is it something that's automatically generated when I create a smart contract, or do I need to go through a specific process to obtain it? Also, would the contract address be unique to each contract, or could multiple contracts share the same address? I'm eager to learn more about this as I'm just starting out in the world of cryptocurrency and smart contracts. Thank you for your time and assistance.
