How are firstprivate and lastprivate different than private clauses in OpenMP?

Question

I\'ve looked at the official definitions, but I\'m still quite confused.

Answer 1

firstprivate and lastprivate are just special cases of private.

The first one results in bringing in values from the outside context into the parallel region while the second one transfers values from the parallel region to the outside context.
