H File Extension
Have a problem opening a .H file? We collect information about file formats and can explain what H files are. Additionally we recommend software suitable for opening or converting such files.
What is the .H file type?
A short for 'Header,' the .h filename extension represents the Header File (.h) file type used in conjunction with several high-level programming languages, including C, C++, Objective-C, and others. A header file (.h) contains function, variable, data type, and other definitions and declarations.
An .h file is a regular text file that contains source code in the C, C++, or other programming language. Header files (.h) are part of a programming project that must be compiled to obtain an executable code.
By referencing an .h file via the "♯include" statement, contents of the .h file (declarations, definitions) can be merged with the main code whenever necessary. The purpose behind having .h files in addition to main source-code (.c, .cpp) lies in achieving modularity and re-usability of the code. With C/C++ libraries, .h files provide function declarations.
H files are normally created, viewed, and edited in a programmer's text editor that provides syntax highlighting or within an integrated development environment (IDE).
