ascii-dencoder is a command-line utility designed to convert strings into their corresponding ASCII codes and vice versa: from ASCII codes to characters. This tool is particularly useful for developers, students, and hobbyists involved in fields requiring ASCII manipulation or understanding.

This tool is provided as source code and can be built using make. By just typing make in the terminal within the code's directory:

make

You should now have an executable named ascii-dencoder. Optionally, you can copy it to a location in your PATH for easier access.

To use ascii-dencoder, run the executable from the command line with the appropriate options.

./ascii-dencoder [OPTIONS] <value>

ascii-dencoder accepts the following options:

• -s, --string <value>:

  • Convert the input string to its ASCII codes.

• -c, --code <value>:

  • Convert the input ASCII code to its corresponding character.

• -h, --help:

  • Display the help message and exit.

• -v, --version:

  • Display the program version and exit.

1. Convert a string to ASCII codes:

   ./ascii-dencoder -s "hello"

   Output:

   The ASCII code of the character 'h' is 104 The ASCII code of the character 'e' is 101 The ASCII code of the character 'l' is 108 The ASCII code of the character 'l' is 108 The ASCII code of the character 'o' is 111 

2. Convert an ASCII code to a character:

   ./ascii-dencoder -c 104

   Output:

   The ASCII character for code '104' is 'h' 

3. Display help message:

   ./ascii-dencoder -h

This will display detailed usage instructions and available options.

4. Display version:

   ./ascii-dencoder -v

This will show the current version of the program.

• The ASCII code conversion accepts numbers between 0 and 255.
• Ensure proper usage of command-line arguments to avoid unexpected behavior.
• This tool is straightforward and does not handle complex text encoding scenarios beyond basic ASCII.
