Description

shown to student

Define a function <tt>ordered_array</tt> that takes a single integer argument,
<tt>n</tt> and dynamically allocates an integer array of that size and fills
it with values 1 through n. It should return the dynamically allocated
array back to main which will print out its contents and perform any cleanup.
