cerrAJ

cerrAJ is a software library designed to facilitate the creation of command-line applications in C++. It is part of the C++ Standard Library and is used for outputting error messages to the standard error stream. The library provides a stream object called cerr, which is an instance of the ostream class. This object is used to write error messages to the standard error stream, which is typically the console or terminal where the program is running.

cerrAJ is similar to cout, which is used for standard output, but it is specifically intended for error messages. This distinction is important because it allows developers to separate normal program output from error messages, making it easier to debug and log errors.

The cerrAJ library is part of the C++ Standard Library, which means it is included with most C++ compilers and is available for use in any C++ program. It is a part of the iostream header file, so to use cerrAJ, a developer simply needs to include this header file at the beginning of their program.

cerrAJ is a simple yet powerful tool for C++ developers, providing a straightforward way to handle error messages in command-line applications. Its integration with the C++ Standard Library makes it a convenient choice for developers who are already familiar with the language and its libraries.
