/******************************************************************************

* 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
