* Why learn C?

** an important family of programming languages

------------------------------------------
         C-LIKE PROGRAMMING LANGUAGES

Many langauges derive their syntax
and semantics from C:

C++

Java

C#

and many others

    C-shell
    Objective-C
    Perl
    PHP
    Go
    R
------------------------------------------
    Java, C++, and C# are among the top 10 programming languages
    in terms of demand and use currently
    (and for the forseeable
    future will also be in demand)

** used widely
------------------------------------------
          C IS WIDELY USED

Especially for:

    Operating systems

    Device drivers

    Scientific software

    Software on new processors

    Output of tools that generate code
    
------------------------------------------
     Examples of OS are: Unix, Linux, etc.

     C was designed to write Unix and its programs, and C is
       intimately tied to Unix (and thus Linux) and vice versa

     A device driver is software that interfaces a computer (or OS) to
     a device, like a printer, network card, video monitor, mouse,
     etc.
     
     C widely used in sciences such as physics and astronomy
     where speed of computation is important

     New processors typically have a C compiler that allows programming

** Internet of Things (IoT) will increase usage

------------------------------------------
  INTERNET OF THINGS WILL INCREASE USE

The Internet of Things (IoT) consists of





Most sensors and actuators are
programmed in


------------------------------------------

     ... sensors and actuators that are connected to the internet,
         like jet engines, streetlights, large trucks, thermostats,
         wearables like smart watches (already)
         and consumer devices such as refrigerators, televisions,
         etc.

     ... C or some variant of C, such as nesC.
