+/******************************************************************************
+* FILE: omp_reduction.c
+* DESCRIPTION:
+*   OpenMP Example - Combined Parallel Loop Reduction - C/C++ Version
+*   This example demonstrates a sum reduction within a combined parallel loop
+*   construct.  Notice that default data element scoping is assumed - there
+*   are no clauses specifying shared or private variables.  OpenMP will 
+*   automatically make loop index variables private within team threads, and
+*   global variables shared.
