Concept Check

0/5

What is the execution order of multiple defer statements in Go?

They execute sequentially as written.

They execute randomly.

They execute in FIFO order.

They execute in LIFO order.

Can a deferred function in Go access named return values?

Yes, it can modify them.

It depends on the function.

No, it cannot access them.

Only if explicitly passed.

What happens if a panic occurs before a defer statement?

It executes after recovery.

The program crashes immediately.

It is skipped entirely.

The defer statement still executes.

How does defer handle file closing in Go?

Defers it indefinitely.

Only if no errors occur.

Immediately closes the file.

Ensures file is closed after function ends.

In Go, can deferred functions call other deferred functions?

Yes, through the defer stack.

No, they run independently.

Only in main function.

It causes a runtime error.
