Version 1.3 (29 May 2025)

This is a simple program written in standard C, dialect C89.  It reads
in the standard input, and prints the byte-for-byte reverse of it on the
standard output.  It can be used on any type of data. It is good for
reversing text input, as long as you are not using "wide characters".

The program should compile on any operating system or type of machine. It
relies only on the standard library. You can use GNU make to compile simply
by typing "make".

This program exists to demonstrate the algorithms used.  You are welcome to
study the source code and the algorithms.

There is an alternative version of this program that uses getchar()
and putchar().  There is also a C++ version of this program.

My thanks to the wizards on the [c-prog] mailing list on Yahoo! Groups, and
kate from IRC, for their feedback.

This project is complete. It is actively maintained by me. The last review
occurred in May 2025.
