differences between:

const int ROWS = 17;
const int COLS = 17

and

enum {
ROWS = 17,
COLS = 17
};

I know not to use macros for C++, but confused as to which to use between these two, which one uses less memory?

const void const printStr const ( const char *str)

a const before function returns const?
const inbetween void and printStr the same?
const before arguments the same as having const inside?

a const pointer is a reference, and a reference is automatically const?

const int ROWS = 17;
const int COLS = 17;

This is good: you have two named constants.

enum {
ROWS = 17,
COLS = 17
};

This was a kludge used in C to avoid #define. You should use enums when you actually need to create a new type with a small set of possible values, not when you need a constant.

const void const printStr const ( const char *str)

This won't compile, you can't use const on the same type twice and you can't put const between the function name and the parameter list.

a const pointer is a reference

No it isn't. But you can obtain a const reference from a const pointer by dereferencing.

and a reference is automatically const?

No, it is as you define it: int& is not const, const int& is.
