What is the .HPP File Extension?

.HPP File Extension Description:

C++ is a middle-level programming language that consists of both high and low level features. It supports data abstraction and several types of programming processes such as procedural, generic, and object-oriented.

A C++ project consists of any number of individual source files and uses the keyword #include in order to indicate the source file that will be duly referenced by whichever given unit and thus actually making the unit's code visible to the calling unit. The project also includes a header file that ends up with the file extension HPP as its format.

Files with the .hpp file extension typically contain the classes' declarations and records or even the substructures in the C++ program. Hence, these stated structures can be accessed by the source files using the keyword #include. Thus, the file #include top.hpp consists of all the classes and structures declared in this file along with any kind of functional declarations given in the so-called header. There is also no indication that the actual code is included in the file with the .hpp file extension - only the header points to such code, in which, this can be found in a separate file.

The use of files with the .hpp file extension promotes code modularity and reusability for the classes and structures. This is because, with the use of the statement #include, records can be simply incorporated into any new application that needs them. The data in these files are utilized by the programmer who needs access to the classes and DLLs, as well as by the compiler that needs these classes incorporated into the precise program. It is files with the .hpp file extension that form the interface between the classes and the programmers' code.

A simple file with the .hpp file extension contains #indef_ARECORD_HPP, #define_ARECORD.HPP, struct somerecord {char name[30]; char phoenum[10]; int age; }; #endif.

The HPP file extension was introduced after C++ came to life, thus, the header convention for C++ headers is newer than the H file extension for C headers. It is usually used in order to define CPP templates that can even be mixed with C objects to some extent.
