Clean ways to write multiple 'for' loops
...) {
// ...
}
(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
{

class iterator : private std::vector<int>::iterator

Scalar vs. primitive data type - are they the same thing?
...imitive objects which contain a single value and are not composed of other C++ objects

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:

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...

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.
...
Should switch statements always contain a default clause?
...switch. Also, in some languages you can assign integer values to enums. In C++ enum MyEnum { FOO = 0, BAR = 1 }; MyEnum value = (MyEnum)2; makes a valid MyEnum instance that is not equal to FOO or BAR. If either of these issues would cause an error in your project, a default case will help you find ...
