I can't connect my Ps4 controller to the PC. What can I do?

So i can connect my ps4 controller in bluetooth to my pc but in fortnite i can't use it what?

Microsoft and Sony are competitors, it's not that simple.

for this you need a third party software or driver

and does your PC have bluetooth or do you have a bluetooth stick?

Have you already connected it with a usb cable?
