H File - opening and understanding
Did your computer fail to open a H file? We explain what they are used for and recommend software that we know can open or otherwise handle your .H files.
What is a H file?
Files that contain the .h file extension are normally header files used with the C or C++ programming languages. .h files are commonly known by programmers as "header files". They may contain constants, function prototypes and external variable definitions.
The header files are included by source code files that need to use the constants or functions defined in the header file. For example, if you define a text string with your company name in a header file, this constant can be used everywhere you need to display or otherwise use the company name in your source code. Should you later decide to change the name, you only have to do it in the header file and recompile to make the change take effect everywhere.
