See http://www.cplusplus.com/reference/algorithm/max/
std::max is a function. It returns a value that is the largest of its input parameters.
The return value is the result of a computation.
All functions do not return values.

If you need a definition just look it up! For instance, the tutorial on this site explains it well: http://www.cplusplus.com/doc/tutorial/functions/
