* OpenMP Example - Combined Parallel Loop Work-sharing - C/C++ Version
* FILE: omp_workshare3.c
* DESCRIPTION:
* This example attempts to show use of the parallel for construct. However
* it will generate errors at compile time. Try to determine what is causing
* the error. See omp_workshare4.c for a corrected version.
