How To Open H Files

DESCRIPTION:

An H file extension is associated with a header file used in the C, C++, Java, and Object-C programming languages. Files of this type are used to segregate program files. The file type can contain variables, constants, or a function used in a program file or project. They denote the particular identity of the file, as well as the function and type of terms. H files make a declaration, and this declaration can be accessed by other files and programs. The file header also contains a guard to ensure that the contents of the header have been correctly compiled. The H file allows common functions to be written only one time and referenced by other files, instead of having to rewrite them every time a new program is written.
