what are header files in c ?
Header files are the predefined files in c which consists the function
definitions of the library functions. These header files are must and
should be included in the program inorder to use inbuilt library
functions in c. we can create our own header files in c to reduse code
work.
what is the use of creating our own header files in c ?
header files are used to store the function definitions. so if your code
is too large, then you can put dome of your function definitions in a
header file and include that header file into your source code at the
time of compilation. This reduces our coding work and increases code
readability.
how to create our own header files in c ?
creating our own header files in c is very easy. If you want to store
the function definition of a particular function in a header file, then
follow the below steps.
step 1:-
step 2:-

readability.
If there is any function which is to be repeatedly used in all the
programs, then it becomes difficult to write the function definition in
each and every program. for example if you want to display author
information at the end of a program for all the programs written by a
particular author, then it becomes hard to display it manually in each
and every program.
so in that case you can store the author information in a function and
save that function in a header file. Now you need to just include that
header file in each and every program to display the author information.
how to create our own header files in c ?
creating our own header files in c is very easy. If you want to store
the function definition of a particular function in a header file, then
follow the below steps.
step 1:-write the function definition in a text file and save it as filename.h. remember to write only function definition. you should not write function prototype and main function. remember the function name you used in the header file.
