Question

Possible Duplicates:
Declaring pointers; asterisk on the left or right of the space between the type and name?
what is the difference between const int*, const int * const, int const *

I’ve been wondering what is the difference between:

float const &var
const float &var

And which one of these is the correct way of writing the code? (including the above example):

float const& var
float const &var
float const & var

and with pointers:

float * var
float *var
float* var

I always put the special marks just before the variable name, feels most logical. Is that the correct way ?

Answer 1

All are equally valid. There is no one correct way; you should do whichever you find most readable (for your own code) or follow the prevailing style (if working with others).

Putting const first (e.g., const float & rather than float const &) is more common in my experience.

The positioning of & and * depends on programmer; no choice seems more common than any other, in my experience.
