the user interaction could be a little better, for example I don't like that when I'm on the Mybox tab, once I open a file and close it I keep getting directed to the dashboard. So I have to keep clicking back to the Mybox. Otherwise, great product! :)

Good Features and Functionality
I have used this software app for every type of editing, creating, and converting imaginable and have yet to have something it couldn't do.
You can use the software for almost any kind of pdf editing, plus document type conversions. It is very easy to use without much training or help.
The most recent update added a step to get to your full document list. Wish they would have left it at the original dashboard where all your docs appeared without the extra click.

For pdfFiller’s FAQs
Below is a list of the most common customer questions. If you can’t find an answer to your question, please don’t hesitate to reach out to us.
Header guards are designed to ensure that the contents of a given header file are not copied more than once into any single file, in order to prevent duplicate definitions.
What are header guards in C++?
Header guards are little pieces of code that protect the contents of a header file from being included more than once. Header guards are implemented through the use of preprocessor directives. The C/C++ preprocessor directives all start with the # character. You are already familiar with some (#include, #define).
What are included guards C++?
In the C and C++ programming languages, an #include guard, sometimes called a macro guard, header guard or file guard, is a particular construct used to avoid the problem of double inclusion when dealing with to include directive.
What is a C++ header file?
C++ classes (and often function prototypes) are normally split up into two files. The header file has the extension of. H and contains class definitions and functions. The implementation of the class goes into the . Cpp file.
How do I use Index in header files?
#index is often used to make header files idempotent by defining a token once the file has been included and checking that the token was not set at the top of that file. This prevents from the multiple inclusion of same header file multiple time. Suppose you have included this header file in multiple files.
What happens if a header guard is omitted from a header file?
If the header guard strictly conforms to the pattern that compilers expect, then inclusions of that header other than the first have absolutely no effect: the file isn't re-read from disk, nor is it re-tokenised or re-preprocessed. This can result in a noticeable, albeit minor, improvement to compilation time.
Can a header file include another header file?
2 Answers. Yes, a header can include another header. But if you are using the Arduino IDE and the headers aren't in the same folder, then you'll also need an #include line for it in the . Ino file.
What happens if a header file is included twice?
If a header file happens to be included twice, the compiler will process its contents twice. The preprocessor will skip over the entire contents of the file, and the compiler will not see it twice. CPP optimizes even further. It remembers when a header file has a wrapper #index '.
