ELI5: Explain Like I'm 5

Sequence point

A sequence point is like taking a break in between steps of something you're doing. For example, when you're brushing your teeth before bed, you might stop and rinse your mouth before continuing to brush. That rinse is a sequence point in your bedtime routine.

In programming, a sequence point is a spot where the computer takes a similar break in between steps. This is important because it makes sure that the computer is doing everything in the right order, kind of like how you have to brush your teeth before you rinse your mouth.

If the computer didn't have sequence points, it might do things out of order and not get the right answer. Just like if you started rinsing your mouth before you brushed your teeth, you might not have a clean smile when you wake up.

So, sequence points help the computer keep things in order and get the right answer.
