In Topic: std::map iterator increment issue

17 November 2014 - 01:12 PM

That means that pointers are not guaranteed to satisfy the "strict weak ordering" requirement for keys in a map, which in turn probably results in undefined behavior.


While this is true for operator<, std::less for pointer guarantees correct ordering (source: http://en.cppreference.com/w/cpp/utility/functional/less).

Yes, I agree with fastcall22.

In Topic: Reference initialization required.

In Python, references are mutable and their labels (referers)are changed to refer to other referents(objects) by using an = operation.

b=30 # Changing object refering-to (referent 30)
del a # Who cares?! b is referring to another object now. Object 20 is garbage collected.  
print b




Python reference are C++ pointers (they are also garbage collected, of course).

In Topic: "Vector" of types? (compile time template)

Have a look at Boost.MPL: http://www.boost.org/doc/libs/1_55_0/libs/mpl/doc/refmanual.html

It provides among other things containers and algorithms for types.
