Como incluir un archivo de extension h

Question

Como puedo incluir un archivo propio de extension .h??

Answer 1

In OnlineGDB, the icon on the far left creates a new file.  If you click it and give it a name ending with .h then you can fill the file with whatever is in the header file.  Then in the main window you can add #include followed by the name of the file in double quotation marks.  Something like this: https://onlinegdb.com/Q2v1GuHdY
