Clarification about memory addresses

[The illusionist mirage]

Hello

What's the meaning of a memory address(I am not asking about definition, I know that it is a location in the memory)?

For example: 0x22ff04

What does 0, x, 2, 2, f, f, 0, 4 sgnify here?

Thank you

The "0x" prefix indicates that the following literal is to be interpreted as a hexadecimal value.

So, 22ff04 is the actual hexadecimal number, preceded by 0x?

Exactly.
