Why are header files not required when using far and near pointers?

In C Programming, header files are required.
It doesn't matter if you are using near pointers, far pointers, both, or neither -- you still need header files.
There is no connection between the necessity of header files and the pointers' size.

Why to use header file to easy know?
in the java as we use the inheritance property in the same way we can get the the inheritance property in c by using the prepared header files( .h files). there a single program in c use the many methods of many header files like math.h give us to use the use of floor(), sqrt() e.t.c. functions..
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.
How can you create a c program without using header file?
C programs do not require header files. If you want a C program without header files, you can simply not create them. However, you may or may not be able to include your non-header file source files.
How many header are using in c programming?
No explicit limit, you can use so many header files as you want.
What is a header file and library function?
header files are predefined in c, they include the all necessary function to u to do your work easy instead of writing a function for printing a message or to read a input form key board we are using the library functions which are in the header files. there are different types of header files depending upon the requirement we use them.
What do you mean by forward declarations in c plus plus?
A forward declaration is simply a declaration of an identifier that will be defined at a later point during compilation. It is quite common to separate declarations from their definitions using header files (.h) and source files (.cpp). The header essentially contains all the forward declarations of all the definitions contained in the source file. It is also common practice to use forward declarations when a header contains pointers to a type, rather than references. If it includes references, then you must include the header file for those references, but if they are pointers then you only need a forward declaration of the type (before it is used) and the actual header that contains the full declaration can be included in the source file instead.
A program in c plus plus will run without an extension name CPP?
Yes. cpp is merely a convention to differentiate C++ source code from C source code, just as hpp is used to differentiate C++ header files from C header files (*.h). But they are just conventions, not rules: you can use any extension you like for both header and source files. For example, there's nothing to prevent you using the cpp extension for a header file. However, using the conventions makes it much easier to organise and recognise your files.
How you can create a program in c without using header files?
It is not that hard, here is an example: int main (void) { return 0; }
Where system header files are stored in c?
This depends on what compiler you are using. For the most common compilers (including gcc) on a *nix system, most standard header files will be either in /usr/include or /usr/local/include. Check your compiler's documentation for how to check and/or modify the search paths.

Why pointers are required?
The most important use of pointers comes when we pass value by reference to any function. You do not need to create a second memory location as in pass by value. You can mofify the original variable by using its address.
What are the uses of macros?
With macros, you can perform long or boring tasks just by a single click or keystroke combination. Also, you would not need to repeat the same action over and over again.
