* what ?

what's the difference between


char *s;

and

char *r[];


and can you convert the second to the first ?

>char *s;

Pointer to character.

>char *r[];

Array of pointers to char

>and can you convert the second to the first ?

Yes, you can convert anything to anything using casts. Whether the result is meaningful (or readable) is another matter. See below -

Code:

---

#include <iostream>

int main()
{
        char * s;
        char * t[3]={"tt","ss","rr"};
        s=(char*)t;
        std::cout << *(char **)s << '\n';
        return 0;
}

---

If you wanted you could 'convert' an element of an array of pointers to a pointer by assigning one of the elements to a pointer -

s=t[0];
std::cout << s;
