How to run and use encode and decode.

What does encode do?

Compresses the input file (default stdin) using huffman encoding. The resulting compressed file is then written to output (default stdout).

If the provided output file does not already exist, it will be created by the program.

What does decode do?

Decompresses the compressed input file (default stdin), reversing the effect of the huffman encoding process. The resulting uncompressed file is written to the output (default stdout).

If the provided output file does not already exist, it will be created by the program.

Command Line Options

encode

Usage: ./encode [options]

A Huffman encoder.
Compresses a file using the Huffman coding algorithm.

USAGE
./encode [-h] [-i infile] [-o outfile]

OPTIONS
-h Program usage and help.
-v Print compression statistics.
-i infile Input file to compress.
-o outfile Output of compressed data.

decode

A Huffman decoder.
Decompresses a file using the Huffman coding algorithm.

USAGE
./decode [-h] [-i infile] [-o outfile]

OPTIONS
-h Program usage and help.
-v Print compression statistics.
-i infile Input file to decompress.
-o outfile Output of decompressed data.

How to build and run the program.

Step One:

Ensure that the files:

"encode.c"
"decode.c"
"defines.h"
"header.h"
"node.h"
"node.c"
"pq.h"
"pq.c"
"code.h"
"code.c"
"io.h"
"io.c"
"stack.h"
"stack.c"
"huffman.h"
"huffman.c"
"Makefile"

Ensure all the files are inside the same directory.

Step Two:

Open the terminal in the directory and type "make" Alternatively you can type "make all" to make all the executables, or "make encode" or "make decode" to make a specific

Step Three:

Use the usage methods of ./encode and ./decode are located above in the "Command Line Options" section

You may also use the -h with the program to print the usage to the terminal instead of looking through the README

Cleanup:

Type "make clean" to delete all derived files except the created binaries. type "make spotless" to delete all derived files includeing the created binaries.
