Hi Damien,
Yeah, I know. C++ has several different data types including chars,
strings, shorts, booleans, longs, double, floats, pointers, integers,
plus several ones Microsoft created for handles, dword flags, results,
etc. When coming from Visual Basic 6 or one of the .NET languages it can
become quite intimidating and overwhelming. However, the reason C++ has
so many different data types is a throwback to the days when programmers
really had to worry about how many bytes they were storing in memory at
any given point in time. If I remember shorts are 2 bytes, longs are 4
bytes, doubles are 8 bytes, etc. An unsigned integer can store any
number from -32,768 to 32,767. A signed integer is something like 1 to
65,534. Anyway, C++ gives you the power really to manage the amount of
data you are storing in memory and use the data type best suited for the
data being stored. Anyone coming from .NET or a language like Visual
Basic take one look at this and freak as they are holy unprepared for
the scope of data types and degree of memory management available to
them. We haven't even began to talk about pointers which Visual Basic 6
and the .NET languages don't even have. It's different and definitely
more advanced programming.

Hi Thomas,
Yes, that does look complicated, but then again for the past week I
have been struggling with various parts of a C tutorial that was
written by a friend of mine. Where in Visual Basic you have strings,
booleans, longs, integers, types and classes, in C you have chars,
ints, shorts, longs, doubles, floats, pointers, structures and even
completely new user defined data types which seem to look more
complicated the more I try to understand it. Philip Bennefall has been
fantastic and has helped me with various parts of it, but at the
moment my brain feels like it has fallen into the fire and turned into
a shrivelled burned up piece of paper *smile*. I seriously wish I had
been taught this language right from the start when I was introduced
to so-called programming 10 years ago.
Regards,
Damien.
