Passing a std::array of unknown size to a function
In C++11, how would I go about writing a function (or method) that takes a std::array of known type but unknown size?

MIN and MAX in C
...ter much trying to figure out, I don't think there's anyway to do this in VC++, but your best best is to try to mess with MSVC++ 2010 new decltype keyword -- but even so, Visual Studio can't do compound statements in macros (and decltype is C++ anyway), i.e. GCC's ({ ... }) syntax so I'm pretty sure...
What does the tilde before a function name mean in C#?
...alize
In C#, the Finalize method performs the operations that a standard C++ destructor would do. In C#, you don't name it Finalize -- you use the C++ destructor syntax of placing a tilde ( ~ ) symbol before the name of the class.

...) {

}
(or just:
for ( auto& elem: m ) {
}
if you have C++11.)
And if you need the three indexes during such iterations, it's
possible to create an iterator which exposes them:
class Matrix3D
{

Scalar vs. primitive data type - are they the same thing?

I'm curious about whether this refers to whether these items would have a value of 'scale'? - Such as counting numbers.

How do you avoid over-populating the PATH Environment Variable in Windows?
...es which modify the path accordingly.
For example, if I wanted to do some C++ development in Eclipse, I would do:
> initmingw
> initeclipse
> eclipse
This is also handy for avoiding conflicts between executables with the same name (such as the C++ and D compilers, which both have a make...
What is the definition of “interface” in object oriented programming
...ponds to a type and obeys various typing rules.
In other languages, like C++, you do not have interfaces. A class itself defines methods, but you could think of the interface of the class as the declarations of the non-private methods. Because of how C++ compiles, you get header files where you co...

How can I read and parse CSV files in C++?
I need to load and use CSV file data in C++. At this point it can really just be a comma-delimited parser (ie don't worry about escaping new lines and commas). The main need is a line-by-line parser that will return a vector for the next line each time the method is called.

How can I link to a specific glibc version?
... Meanwhile at least one can often resort to musl-libc, but with C++ programs things can get more complicated, so specifying a symbol version may be necessary still.
