What's your favorite C++0x feature? [closed]

Answer 1

Smart pointers. It really makes a world of difference not having to explicitly memory-manage heap-allocated objects.

Obviously you still need to "know what you're doing", but in my experience it has decreased the number of memory-related bugs at least one order of magnitude in software I've worked with.

Answer 2

1. It has to be the incorporation of some of the Boost libraries (shared_ptr<> and bind top the list)

2. Control over template instatntiation should finally solve the issue of the enormous compile times and make it actually feasible to use modern template code in large projects.

3. Template typedefs

Lots of other small but important things, but they do matter in production code.

Answer 3

Closures for me.

Answer 4

auto keyword

Answer 5

The syntax going from bad to worse.

Variadic templates and lambdas are nice, though the syntax of both is unfortunately pretty objectionable.

Answer 6

It's not big, but I'm loving the idea of a true nullptr. Should have been a keyword right from the git-go.
