How to find BTC address?

I'm a bit new to the cryptocurrency world and I'm trying to understand how things work. Could you please tell me how I can find a Bitcoin (BTC) address? I've heard that it's essential for receiving and sending payments in the Bitcoin network, but I'm not sure where to start. Do I need a special software or an online service? Or can I generate one myself? Also, how can I ensure the safety of my BTC address and prevent it from being misused? I'm really keen on learning more about this, so any detailed information or resources you could recommend would be greatly appreciated.
