Why can't variables be declared in a switch statement?
...
Yes, but it is not illegal in C (at least gcc says it's not). j will be uninitialized (have some random number), but the compiler compiles it. However, in case of the switch statement, the compiler won't even compile it and I fail to see the difference between ...
C++ lambda with captures as a function pointer
... we can't do much as plain C does not support universal references, but at least we can forward values back to our lambda. This may save an extra copy. Has edited code.

Can I protect against SQL injection by escaping single-quote and surrounding user input with single-
... (albeit not when passing the query to SQL Server using ADO or ADO.NET, at least -- can't vouch for all databases or technologies).
The snag is that you really have to be certain which strings contain user input (always potentially malicious), and which strings are valid SQL queries. One of the tr...
What is getattr() exactly and how do I use it?
...he hood of Pylons's routing, for instance, you'll see that (by default, at least) it chops up a request's URL, like:
http://www.example.com/customers/list
into "customers" and "list". Then it searches for a controller class named CustomerController. Assuming it finds the class, it creates an in...
Is 'float a = 3.0;' a correct statement?
...float, so float a = 3.0; is a valid definition of a variable.
However, at least conceptually, this performs a needless conversion. Depending on the compiler, the conversion may be performed at compile time, or it may be saved for run time. A valid reason for saving it for run time is that floating-...

To accomplish that, people have invented MinGW and MSYS - a minimal set of build tools to develop programs on Windows in an Unix-like fashion. MSYS also contains a shared library, this ...

Why can't I define a default constructor for a struct in .NET?
... executed in all cases - but that would have led to more confusion. (Or at least, so I believe the argument goes.)
EDIT: To use your example, what would you want to happen when someone did:
Rational[] fractions = new Rational[1000];
Should it run through your constructor 1000 times?
If not, we...
