iterators

C++ does a very good job, though, by making iterators look like pointers.) The problem is that, in C, the primitive types don't specifically describe their sizes.

Look at iterators: they're obscure and complex if you've never encountered them, but now they seem really easy.

You will start with basic things like iterators and work through some algorithms and the basics of object-oriented programming.

You need iterators, you have map, which is just a function the user can define, etc.

For example, an algorithm can take an arbitrary Iterator type, and select between a correct-but-slow algorithm for weak iterators like forward iterators, and a fast algorithm for strong iterators like random-access iterators.

The problem isn't that 'int' is the default type, not 'long', nor is it that array indexing isn't done with iterators.

In particular, if one is advanced programmer in general, or at least has a firm grasp of Python basics, iterators are nice.

There is a legitimate complaint with that specific example, though: having to write.begin() and.end() is obnoxious instead of using more modern iterators/ranges.

It's pretty clear using int indexes or pointers, but iterators can get verbose.

Reading your comment I initially assumed {i, j} were iterators, in which case they would be fine by me.

Traits and proper generic types, iterators and pattern matching all contribute to this.

That problem is due to the STL not being built around iterators/ranges.

You get the cognitive overhead of dealing with memory management and pointer arithmetic and iterators, but the options for not working with them when you don't want to are limited - so it's hard to concentrate on the functional level, and you do a lot of the work the compiler/interpreter would usually do, but without the "do whatever you want" freedom of assembler.

Iterators and yield -- First introduced in CLU are now common in modern languages.

Iterators: create a separate iterator type with e.g.
