Ok so i mistyped. Just make it this and it will work (i think)
sizeof(*names)/sizeof(string)

Happy?

P.S. btw i know to pass the length of a dynamic array or to use vector but im just...

The easiest way to get the length of a dynamic array is this

sizeof(array)/sizeof(arraytype)

where array is your dynamic array and arraytype is the data type (for instance int)

Hope...
