esp8266, const char* ssid = "ssid" VS const char *ssid = "ssid"??

const char* ssid = "ssid"
OR
const char *ssid = "ssid"

Total newbie here just wondering which one is right when setting up a wifi connection? Or it doesn't make a difference?

I keep seeing it both ways in other peoples code

They are equivalent and declare a pointer to the ssid variable

thank you

I think this is better since it makes it explicitly clear that you're creating a constant char array:

const char ssid[] = "ssid";

But, if you insist on using the pointer notation, then use this to prevent your code from accidentally changing the pointer's value.

const char * const ssid = "ssid";
