/******************************************************************************
* OpenMP Example - Combined Parallel Loop Work-sharing - C/C++ Version
* FILE: omp_workshare4.c
* DESCRIPTION:
* This is a corrected version of the omp_workshare3.c example. Corrections
* include removing all statements between the parallel for construct and
* the actual for loop, and introducing logic to preserve the ability to
* query a thread's id and print it from inside the for loop.
* SOURCE: Blaise Barney 5/99
* LAST REVISED: 03/03/2002
