V710. Suspicious declaration found. There is no point to declare constant reference to a number.

Nov. 11, 2014

The analyzer has detected a suspicious code fragment where a constant reference to a numerical literal is created. This operation doesn't have any practical sense and is most likely to be a consequence of some typo. It may involve using a wrong macro or something else.

A couple of examples:

const int & u = 7;
const double & v = 4.2;

You'd better not suppress this warning but eliminate it by deleting the ampersand character thus turning the reference into a regular constant value (of course, you should check first that it all was meant exactly that way):

const int u = 7;
const double v = 4.2;
