How can I create a header file in C++?

Answer 1

Open notepad and write the function that you want to use.
Now save the notepad file with .h extension.
as we are creating a function for sum, so save this file with name sum.h in
INCLUDE or BIN folder (you can use any other name).
After that write a program that uses this sum function and
include the header file that you have just created.
