It is the world’s simplest substitution cipher, where A becomes B, B becomes C, and so on. Don’t use this encryption for anything that is of value. Please note, this is a quick and dirty hack for demonstration purposes. The purpose of this library is to encode strings of text and to decode encoded text. To do that we need a requirement for the static library to fulfill. We’re going to run through the steps required to create and modify a static library, and demonstrate how to use the library in a program. And ar is also be used to create package files such as the “.deb” files used in the Debian Linux distribution and its derivatives such as Ubuntu. The ar command is still used for a few specialist purposes, though. That role has been taken over by other utilities such as tar. People looking for that type of functionality no longer turn to ar. Files can be added to, removed from, or extracted from the archive. An archive file is a single file that acts as a container for other files. The name ar references the original intended use for the tool, which was to create archive files. The ar command is a real veteran-it has been around since 1971. This tutorial will show you how to create a static library, modify it, and use it in a program, complete with sample code.
Use Linux’s ar command to create function libraries when you’re developing software.
