This time I want to look at a seemingly trivial concept in C++ programming: accessing class members, either directly or via a pointer.  More than anything it’s an excuse to talk about two of C++’s more obscure operators – .* and

Enumerated types in C++ give a trivial simulation of symbolic types – that is, objects whose instances have unique, human-readable values. In C++ enumerations are essentially named integers that are either assigned values implicitly by the compiler or explicitly by the programmer (or a combination of both)

C++ enum types inherit their semantics from C with some additions:

enum objects are now first-class types
enums may be implicitly converted to integers; but the reverse is not true

Another characteristic illustrated in the […]

A new (but not so welcome?) addition

Lambdas are one of the new features added to C++ and seem to cause considerable consternation amongst many programmers. In this article we’ll have a look at the syntax and underlying implementation of lambdas to try and put them into some sort of

Iterating through containers… options, options options.

Iterating through a container of objects is something we do a lot.  It’s boilerplate code.  It’s also a nice indicator of how C++ is raising the level of abstraction in programming.

So let’s start with a simple container of ADTs:

Now let’s iterate through them, calling the mf() method on each object in turn.  First, we’ll ‘roll our own’ loop.

That’s imperative programming in action; and has the warm, fuzzy feeling of recognition for all C programmers.

Modern C++, […]
