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