How does this return syntax work?

[hazy parcel]

So I am looking through a code and see this syntax in the return of functions. I dont know how to google for it, so I am asking here.

Syntax in question:

return fIterator ? fIterator->Next() : nullptr;

If fIterator is true it returns the object before :

If false it returns nullptr

So this has little to do with the return statement, and instead what I think you are refering to is the ternary operator

<condition> ? <expressionA> : <expressionB>

This evaluates to expressionA if the condition is true, or expressionB if the condition is false

Just what i said 😅

also in this case fIterator is a pointer. So checking ”fIterator” basically returns true if the pointer isnt 0 (aka nullptr).
