FILE_NAME_SEQUENCE <br> Create an Increasing Sequence of Filenames
</h1>
<hr>
<p>
<b>FILE_NAME_SEQUENCE</b>
is a C++ library which
demonstrates ways of generating a sequence of file names
with an embedded index that increases.
</p>
<p>
There are situations such as animations or parallel processing in which
it is necessary to generate a sequence of file names which include
an embedded index that increases. A simple example might be
<pre>
"fred0.txt", "fred1.txt", "fred2.txt"
</pre>
A side issue arises when the number of files is large enough that the
number of digits in the index will vary. Thus, if we are going to have
15 files, do we want to number them as
<pre>
"fred00.txt" through "fred14.txt"
</pre>
which means, for one thing, that they will alphabetize properly, or
will we be satisfied with
<pre>
"fred0.txt" through "fred14.txt" ?
</pre>
