How to make header files

Question

if we want to make a header file...how?

Answer 1

a header file has the extension .h Saving a file with this extension will make the IDE to interpret it as a header file

Answer 2

Header files can be created by making a program with functions and then saving it with ".h" instead of ".cpp"
then go to the folder where program was saved and copy your saved file to folder where other include files are kept.
To use a function in that header file include that header file and just call the function like you call anything else {like: exit(); or strlen();}
caution: do not define a main function in header file or it will show show error while execution.

Answer 3

do not forget to protect the header from multiple inclusion !
#idndef _MY_HEADER
#define _MY_HEADER

// put your defines etc here !

#endif
