Pointers and Arrays in C - Extremely confused -

this question has answer here:

i have learned traditional way of declaring character array follows:

char c[] = "john";

however, have noticed can declare as:

char *c = "john";

how work? know has pointers, please elaborate? appreciated.

in first example, c array of char. in:

 char *c = "john";

c here not array pointer (type char *) string literal. pointers , arrays different types in c.

below link if want learn pointers , arrays:
