Question

Lets say I have the following variables:

char c[] = "ABC";
char *ptr = &c;
char **ptr2 = &ptr;

I know I can iterate over a pointer to an array of char, this way:

int i;
for(i=0; i<3; i++){
    printf("TEST******************, %c\n", ptr[i]);
}

How do I iterate over a pointer to a pointer?

Answer 1

For your example:

int i;
for(i=0; i<3; i++){
    printf("TEST******************, %c\n", (*ptr2)[i]);
}
