What is the difference between char* and char arrays in C++?

char* is a pointer that points to the first address of a character array. It can dynamically allocate memory to store the character array, point to an existing character array, and change the pointing position as needed.

A `char` array is a fixed-length character array with a predetermined size that cannot be changed, nor can it be directly assigned to another array. Copying characters one by one through a loop is necessary to achieve this.

Therefore, char* is more flexible as it can allocate memory dynamically for easier handling, while char arrays are static, with fixed length and less flexibility.
