Assembly code vs Machine code vs Object code?

Question

What is the difference between object code, machine code and assembly code?

Can you give a visual example of their difference?

Answer 1

I think these are the main differences

• readability of the code
• control over what is your code doing

Readability can make the code improved or substituted 6 months after it was created with litte effort, on the other hand, if performance is critical you may want to use a low level language to target the specific hardware you will have in production, so to get faster execution.

IMO today computers are fast enough to let a programmer gain fast execution with OOP.
