Problem: explained in the MSDN documentation: the operator= operator returns a reference by default-- type& type::operator= (const type&) Why, then? My understanding of this is that "=" is a binary operator. The arguments passed in are reference

When there are several variables involved in the operation, the result type depends on the variable type that represents the largest range in the variables. For example, in the variable that participates in the operation, there is an int, a double
