If you're after the difference between the two, just think of them as:

• char* is a pointer that points to a location containing a value of type char that can also be changed. The pointer's value can be changed, i.e. the pointer can be modified to point to different locations.
• const char* is a pointer, whose value can be also changed, that points to a location containing a value of type char that cannot be changed.
