Everything is easy to use
Everything is easy to use. I was having some issues faxing and got a quick response from support. Other than that great experience so far. It would be cool if I could request documents from clients where they can upload and it would go to my docs in pdf filler.

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.
#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 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 '.
How can you avoid including a header more than once?
How can you avoid including a header more than once? One easy technique to avoid multiple inclusions of the same header is to use the #index and #define preprocessor directives. When you create a header for your program, you can #define a symbolic name that is unique to that header.
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.
How do you use header guards?
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).
How do you use 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 do header guards protect against?
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. Note that header guards do not prevent the contents of a header file from being copied (once) into separate project files.
