Unnecessary curly braces in C++?
...scope, where you can more "cleanly" declare new (automatic) variables.
In C++ this is maybe not so important since you can introduce new variables anywhere, but perhaps the habit is from C, where you could not do this until C99. :)
Since C++ has destructors, it can also be handy to have resources ...

Why do I have to access template base class members through the this pointer?
...e compiler be able to resolve the grammar of the code in the template.
In C++ (and C), in order to resolve the grammar of code, you sometimes need to know whether something is a type or not. For example:
#if WANT_POINTER
typedef int A;
#else
int A;
#endif
static const int x = 2;

Significance of -pthread flag when compiling
In various multi threaded C and C++ projects I've seen the -pthread flag applied to both the compiling and linking stage while others don't use it at all and just pass -lpthread to the linking stage.

Differences between unique_ptr and shared_ptr [duplicate]
...late parameters.
unique_ptr is also what auto_ptr wanted to be in the old C++ but couldn't because of that language's limitations.
shared_ptr on the other hand is a very different animal. The obvious difference is that you can have many consumers sharing responsibility for a dynamic object (hence ...
Why are there no ++ and -- operators in Python?
... I've encountered (more than anyone should in their life) a fair amount of C++ code suffering from problems with ++ and -- being used in ways that result in undefined or unspecified behavior. They make it possible to write complicated, difficult-to-correctly-parse code.

Can I use a binary literal in C or C++?
...
You can use BOOST_BINARY while waiting for C++0x. :) BOOST_BINARY arguably has an advantage over template implementation insofar as it can be used in C programs as well (it is 100% preprocessor-driven.)
To do the converse (i.e. print out a number in binary form), yo...
