What is the different between header file and header pointer?
Header file is a file which is meant to be included into another file during compilation. Examples: string.h, stdio.h, inttypes.h. Header pointer is a pointer to an object called header (for example header of a linked list).
How do you include a system header file called sysheader.h in a c source file?
There is no system header called share.h, but if there were, it would be: #include <share.h>
Can Header file be called in main function or not?
No, main.c does not require a header file. When you have a ".c" and ".h" pair, the ".h" file is to declare the existence of functions that are defined in the ".c" files so that these functions can be called in other files. since "main.c" needs the headers of the other modules (to access their data types and functions) but usually doesn't have a header file itself.Header files aren't "called", they are "included",but usually not inside any function.
Why you use header files in c?
the use of header files is to add functionality. Header files are basically saying put code in that header file here so you don't have to type that many lines of code.
Which header file is FILE declared in?
The FILE type is declared in stdio.h.

How do you create an header file in c with example?
Any file can be called a header. Whenever someone uses #include , it's the same as copy/pasting that file in that spot. Typically though, they call it a header if it's included at the beginning of your source.
What is the header file of graphics?
The header file of graphics in TurboC is graphics.h
Is header file the library file?
No. Header files are those which contains declaration part of function & library files are those which contains definition part of function. These are those functions which we called in our program by using header files.
What is a header file?
There is no such thing as 'total header', maybe it is a term only used by your teacher, so ask them directly.

How do you create a user defined header file?
Header files are not much different from usual cpp files. There are basically two different things. It's file extension: you need to choose "header file" when you create it or save as .h file. Second is header files do not have main() function. When you are done with you header file do not forger to include it in your project by writing preprocessor directive:#include "your_header_file.h"
If a file header is lost or corrupted and an application needs that header to read the file how can you recover the contents of the file?
Not possible. Always make backup copies.
When is header file executed and why?
Never, and the reason is that header files are not meant to be executed.
