If you have additional information about the H file format or software that uses files with the H suffix, please do - we would love hearing from you. We spend countless hours researching various file formats and software that can open, convert, create or otherwise work with those files. 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. . They may contain constants, function prototypes and external variable definitions. Plus, don't miss out on all your Member rewards, birthday offer and special invites to events!
