How works char* ?

Question

the c++ challenge have some queations about this

like:

char* var = "abc";
char* var2 = ++var;
return *var2;

Answer 1

I undestand char* now is a pointer of an character into a "string"

and ++var move the pointer one character to the right.

if we dont use the * before the variable name it return all the characters from the actual pointing character ot the last.
