What is the .HH File Extension?

.HH File Extension Description:

Files that have an .hh extension are header files for the C++ Programming Language. These files are referenced by C++ source codes, and are developed by Borland, a software company best known for its IDE, or Integrated Development Environment businesses.

HH files, also termed as "include" files, are typically in source code forms that are automatically included by a compiler for another C++ source file. Files with the .hh extension are usually placed at the head or beginning of the other source file, with the syntax - #includes "<header filename>".

Header files, ending with the .hh file extension, can contain subroutines, forward declarations, variables, and other identifiers used in the C++ programming language. Subroutines, also known as methods or functions, are a block of codes within a larger program that performs tasks that are specified by it. Functions are usually broken down to a body of executable codes, parameters to be passed, and a return value.

Forward declarations are declarations of variables or subroutines that do not yet have a specific definition. Variables, sometimes referred to as objects or identifiers, are symbolic representations referring to a quantity, value, or expression, all of which are housed by HH files.

An HH file is generally declared with the C++ Standard Library, which is a collection of functions and classes written in C++, and provides a number of generic methods to be used. The library that HH files use can hold containers, iterators, algorithms, subroutine objects, and so on.

A number of standard declarations, used by .hh files include "ios", "bitset", "locale", "string", and "numeric". <ios> offers several basic functions and types of input/output operations. <bitset> is a container that is a bit array. <locale> is a general declaration used by HH files to provide classes to a set of parameters defined in C++. <string> is a header file that offers standard C++ string templates and classes; and <numeric> provides numerical processing algorithms.
