C++, originally C with Classes, was a great idea. It added Smalltalk
like abstractions to data and bound data to methods. This is long in the
past and I no longer use C++. C, in its ANSI/POSIX/ISO incarnation is
quite good. Modern C has removed some of its FORTRAN roots and fixed
many of the K&R foibles.

Pointer arithmetic is what C is all about. The original manual and the
Programmer's Workbench both call it a portable assembler.

There are no arrays in C, there is a memory region that is addressed by
a reference. Pascal and its derivatives (Modula, Ada) do implement real
arrays as does PL/I.

For scripts, I use byte code languages (Perl mostly these days) with
some low level modules written in ANSI C. I do however, miss using
FORTH, CLOS and Smalltalk for real applications.

Most applications that are not critical to latency or 6 sigma
predictability are best served with a byte code language. This places
the burden of reliability on the developers of the run time (byte code
machine). That said, I have probably written as much code in various
assembly languages as in C.

I have been using Unix and its analogs for 37 years, computers for
engineering for 51 years. My first programs were written in FORTRAN-4,
using a model 19 key punch.
