/* File:     out_of_range.c
 * Purpose:  Illustrate what happens when an array subscript is out of
 *           bounds.
 *
 * Compile:  gcc -g -Wall -o out_of_range out_of_range.c
 * Run:      ./out_of_range
 *
 * Input:    None
 * Output:   Depends on the system
 *
 * Notes:
 * 1.  The final assignment will probably cause a segmentation fault, which
 *     may result in lost output.  To avoid this, add fflush(stdout) after
 *     the printf statements.
 * 2.  Global int i prevents assignments in for loop from overwriting i
 *     (at least on MacOS X).
 * 3.  You may need to experiment with the upper bound for the loop and
 *     the subscript for the assignment x[10] = 82.
