What are forward declarations in C++?
...really just allows the compiler to do a better job of validating the code, and allows it to tidy up loose ends so it can produce a neat looking object file. If you didn't have to forward declare things, the compiler would produce an object file that would have to contain information about all the po...
Is there a constraint that restricts my generic method to numeric types?
...ons for not implementing the feature in an interview with Bruce Eckel:
And it's not clear that the added complexity is worth the small yield that you get. If something you want to do is not directly supported in the constraint system, you can do it with a factory pattern. You could have a Matrix...

How do you effectively model inheritance in a database?
...s has its own table. The base class has all the base class elements in it, and each class which derives from it has its own table, with a primary key which is also a foreign key to the base class table; the derived table's class contains only the different elements.

Java JTable setting Column Width

and the change - or "delta" - should be distributed to all of the columns regardless of
this JTable's automatic resize mode.
This might be why AUTO_RESIZE_LAST_COLUMN didn't help you.
Note: When a JTable makes adjust...
How can I perform a culture-sensitive “starts-with” operation from the middle of a string?
...
I'll consider the problem of many<->one/many casemappings first and separately from handling different Normalization forms.
For example:
x heiße y
^--- cursor
Matches heisse but then moves cursor 1 too much. And:
x heisse y
^--- cursor
Matches heiße but then moves cursor 1 to...
C++11 reverse range-based for-loop
...e key observation is that range-based for-loops work by relying on begin() and end() in order to acquire the range's iterators. Thanks to ADL, one doesn't even need to define their custom begin() and end() in the std:: namespace.
Here is a very simple-sample solution:

multidimensional arrays, and jagged
arrays (arrays of arrays). All array
