Learning how to program software seems like a
daunting task fit only for the geeks and nerds who lock themselves away
in dark rooms staring at their monitors for days on end as they pour
over thick manuals written largely in zeros and ones. Fortunately the
reality is that it’s not as complicated to make basic applications as
people may think. If it were, the majority of nerds wouldn’t be doing
it because the defining factor of our kind is an inherent laziness. Why
do you think we like computers? The heaviest thing we have to lift is a
monitor and that’s done fairly irregularly and for a very short period
of time.
There are many different opinions on how you should
start programming. Some advocate the method of throwing yourself firmly
into the deep end and if you don’t drown then you’re set for life.
These people usually recommend getting stuck straight into C or C++.
Others recommend a slightly easier starting point such as Java or C#,
still quite involved but with a few more safety nets built in. Then
there is the ‘kiddy pool’ school of thought that advocates such
languages as Visual Basic. These languages are really easy to get
started in. You drag a few elements onto a blank form and then write
some code that reads largely like Standard English. All methods have
their advantages, but I’m a fan of starting somewhere in the middle
with Java. My reasons for this are that Java enforces a certain amount
of design and forethought as well as correct programming procedures
that are somewhat absent from Visual Basic.
I can’t go into every
single language in one article because it would take too long and the
only experience I have with languages outside of the Microsoft stable
is some familiarity with Java. Here are a few details about some
languages.
Java Programming in Java is very similar to C/C++
development. It is object-oriented and well structured. There is wide
usage of Java, and therefore there are a lot of libraries around that
can be used in your Java program.
Pros:
· Java is platform independent, it can be run on everything.
· It’s free, you can just download the SDK and go.
· It’s easy to learn if you know C or C++.
· It provides automatic memory management.
· There are a large library of pre-built classes and many more available from around the net.
· It’s quite safe. It’s fairly hard (if not impossible) to damage your computer through programming in Java.
Cons:
· Speed. Java is quite slow, because it is essentially compiled at run-time by the system’s virtual machine.
· It is difficult to compile into a stand-alone application.
· Memory pointers are not allowed.
· Some people dislike being forced into object oriented programming.
C
C has been around for years and has a large following. Many different
people around the globe use it. A few other programming languages have
also been written in C.
Pros:
· Large usage base. Easy to find help, other programmers, libraries
etc. · Simple core language, with further functionality being added
through the use of libraries. · Very powerful. If your computer can do
it, it can do it through C. · Low-level unchecked access to computer
memory using of pointers. · One of the fasted running languages. · C
code can be used in C++ applications. · Programs are compiled and stand
alone, no need for interpreters (sometimes external libraries will need
to be installed on the target PC).
Cons:
· Relatively difficult to learn. · Very little safety net. If you
choose (accidentally or otherwise) to make a program that will access
memory incorrectly and horribly break your system, it won’t stop you.
It only pulls you up on compile errors. · Non trivial programs could be
hard to port. Programs have to be compiled for each specific platform.
· Not strictly object oriented. · Code can get messy easily.
C++ C++ is a derivation of the C
programming language. C code still works in C++ programs. It is an
object-oriented language and very powerful.
Pros:
· As close to a universal programming language, as you’re likely to get at the moment. It’s used everywhere.
· Object oriented technology included, highly supported and recommended, but not forced upon you.
· Programs are stand alone, no need for interpreters (sometimes external libraries will need to be installed on the target PC).
· Easy to port to other platforms if standard C++ guidelines are adhered to.
· Many libraries available for added functionality.
Cons:
· Quite difficult to learn. You’ll never really stop learning new things about it (which is also a pro, I guess).
· Non-trivial programs aren’t easily ported if they use platform-specific libraries (e.g. DirectX etc.).
· Programs can be slightly larger and slower than those programmed in C.
Visual
Basic Visual Basic is a very easy language to use. Its code is similar
to Pseudo-code and many times the developer can simply type what they
think should work and it does, which is cool.
Pros:
· Very easy to learn
· Quick to implement an application or algorithm
· Lots of in-built functionality
· Recently added complete OOP support with the .Net upgrade.
Cons:
· Not as flexible as other languages, you can’t do as much.
· Runs slower than C/C++
· Purely a Microsoft product and Windows based.
Where
you start is largely up to you and what you want to get out of your
programming. If you want to make it a career you’re going to want to be
familiar with the more ‘industrial’ programming languages such as C and
C++. There are still a lot of people out there experienced with these
languages but you’ll be in a more specialized field. You’d have trouble
throwing a punch in a crowded room without starting a scuffle with
someone who could get a program going in Visual Basic. Start with a
language that is suited to your skill level and when you’ve learnt a
bit of that you’ll find it easier to move on to other languages. I’ve
found personally and within my group of peers at university that now
that we all have a certain amount of programming knowledge, it really
doesn’t take much effort to get stuck into another language and code a
program there. Most of our assignments are done through improvisation
as we learn the specifics of a language necessary to implement the
assignment. You may not get a program as cohesive and well written as
you would like compared with if you had a better idea of what you are
actually doing, but it usually works.
Don’t let me kid you into
believing that you can develop software with the utmost ease. You’ll be
sitting there staring at just three lines of code for two hours
wondering why it doesn’t work before you realize that your
capitalization is wrong. However, it is a very rewarding feeling when
you do get to the end of a program and it all works beautifully (at
least until the user base get their hands on it and break it). So if
you’re even somewhat interested get in there and have a go. The worst
that can happen is that you’ll rewrite your boot sector.
