Botanists describe plant species and distinguish them from The most direct means of confirming botanical identity is by How do you confirm the identity of a plant?

On the other hand, the declaration char *p = "abc" ĭefines p with type "pointer to char" and initializes it to point to an object with type "array of char" with length 4 whose elements are initialized with a character string literal. The contents of the arrays are modifiable. If you are just printing the two examples, it will perform exactly the same.
The difference between char* the pointer and char the array is how you interact with them after you create them.
