C++ in Review

I started learning C++ back in September, and I think I've experienced enough of it in order to write a proper review post on it. I've been wanting to do this for a while, as I have quite a bit to say about it.

I think I should start off by saying that C++ is complicated. Very complicated. To the point that you could learn about it for years and still not be half way through everything that you could learn about it. While this offers unparalelled customisablility, it also makes it difficult for new programmmers to pick up the language. Even worse is that whilst something might work, it could easily contain a critical security bug that can be extremely difficult to spot.

It's also difficult (for me anyway) to remember what everything is and what it does. For example, a const int* is not the same as an int* const. I find myself constantly looking things up that I forget over and over again. On top of this, a large number of the core built in functions don't actually do what you'd think they would. For example, getline() doesn't get a line of text, and fail() checks to see if an error occurred whilst opening it. These names can't be corrected in a later version of C++ either - later C++ versions must be able to compile previous versions of the language, including pure C from 30 years ago. Perhaps this is what makes it so difficult to use?

The other thing that makes C++ annoying and difficult to use is how low level it is. You end up having to do almost everything yourself - even things that you'd think would be built into the language already. The standard template library (STL) provides a large number of methods and data strutures to fill in the gaps, but most of these are misnamed too (the vector class is actually similar to a C♯ List), so you end up implementing your own anyway because you can't find the class you want in the STL (only to have someone point it out later).

Thankfully, there is a reason why everyone is still using an old broken language to write important code - it's practically the fastest language out there short of assembly language. No other language comes close to rivalling C++ in speed. Is this the only reason we are keeping it?
