You need an USB-C to USB-A cable... the one that comes with your charger should do just fine IF your computer has USB-A ports (AKA 'normal' USB ports). If you have a new computer with USB-C ports (like a Samsung tablet or the new Macbooks) then you need a male-to-female USB-C cable (which doesn't come in the box and you'd need to buy).
The cable that comes in the box is all USB-C...
Oh, crap! Thanks for that correction... in that case, OP, you should have what you need in the box if your computer has an USB-C port! I'm told there is also an A-to-C adapter in the box, but that is Female-A to Male-C, so that won't work if you have 'normal' ports. For that you'd need a Male-A to Male-C cable. And that's the one you'd need to buy.
No you are totally wrong. The adapter in the box is is usb-a to usb-c. You can get a c to a adapter from Amazon for a few quid for 3.
