The castings above are completely unnecessary in C.


E.g.

str_arr = malloc(num_of_elements*sizeof(char*));


In C, a void * is implicitly converted back to any pointer type.

Re: [Dev-C++] Hi! Issues relating to DirectX 9.0 and DevC++

[Daniel G. <sp...@ho...>]

For DirectX 8.0 someone had written the .a library files to make the samples 
compile (from microsoft) but not sure about 9.

DirectX never worked for me in the last version of Dev-C++, I had to buy 
VC++ 6.0.

Your thoughts are right, but the thing that produces compilation error, 
maybe the malloc/realloc/calloc thing associated with them:

//for char**:
char **str_arr;
int num_of_elements = 5;
str_arr = (char**) malloc(num_of_elements*sizeof(char*));

//the for each element of that array you should malloc
str_arr[0] = (char*) malloc(10*sizeof(char);

...

Hope that helps.

Yes they are.

The third. Yes, it is a pointer to char *. Or a pointer to pointer to =
char.

char * points to a char variable. This variable can be part of a =
sequence of
chars (an array) either on the free store either in the automatic =
storage.
But it can also be alone.

[Dev-C++] One other minor problem

[Shane P. <ge...@my...>]

I also have one other minor problem.

Though I have looked through over 16 different manuals and tutorials, and have searched over 50 websites I cannot seem to find out the difference between

char* foo;
char *foo;
char* *foo;

From my own expirements (purposely generating compiler errors) it appears to me that the first two are identical.  They both seem to declare foo to be a variable of type char*.  The second seems to declare foo a pointer to type char*.  It also appears to me that type char* is actually a char[] of dynamic length because I can get string functions to work on it - just like on char[].

I have found no confirmation of any of this though.  I would appreciate any info anyone has about this.

[Dev-C++] Need help editing resources.

[Shane P. <ge...@my...>]

Hi, My alias is Gebnar, I am new to this mailing list.

I know this is probably a stupid question.

The Dev-cpp help file says:
"To open the Resource Editor, click on the Project menu, then on 'Edit resource file'."

My version of Dev-cpp (4.9.8.0) is the latest but I cannot find this menu command, nor can I find a resource editor anywhere.  I have learned a little about doing it by hand but an editor would be nice!

If anyone knows anything about this please send me whatever info you have.

Sincerely,
     Gebnar

RE: [Dev-C++] [q] Does C++ promote bad programming?

[Shayne K. <err...@ne...>]

This might have been mentioned before, but just in case, here is my view
on C++.

First of all, C++ is a tool.  And as any tool, you use it appropriately
with the problem.  I think the first mistake new programmers make is the 1
tool fits all paradigm.  Though, this is not specific to C++.

The other thing I see is poor design.  This is easy to do in C++ since you
can implement your application however you want.  There is nothing
stopping you from not using classes/inheritence/etc.

Though, this brings me to another point, mostly about not using the tools
in C++ to its full advantage.  C++ has many useful tools, STL, Templates,
multiple inheritence, Strings, exceptions, etc.

And finally, take a C coder and make them write a C++ application.  I
remember when I did this and I just wrote my C++ applications as C.  They
compiled, but again, they didn't use C++ to its full advantage.
I think over all if you use good design and write a C++ app correctly, the
efficiency will be the same as writing it in C (for example).

If you want to learn C++, learn it.  But take an OO methods course like
intro to objects.

Not only. I use it also because it is the best general purpose =
programming
language. :)

I did not say we should not use pointers. Of course we should where it =
makes
sense. I just answered to the claims that in Java it is easier or safer =
to
do things than in C++. Because it isn't. C++ implements all the =
supported
paradigms well.


The main misconception many people have regarding C++, is that it is =
unsafe
because they use its low level parts when it is entirely unnecessary.
Another crucial misconception is that many peope think programming is =
easy
and find facilities which exist to enable certain things as "difficult",
missing the techniques that they exist to support.

Let's not forget the real reason why we use c/c++: speed. :-)  It's not for
its easy way of coding programs.  So, why wouldn't you use pointer if you're
using c/c++?

In that sense, in all programming languages there is no way to avoid
pointers.

No, you seem to miss all the safety C++ provides. If you want range =
checked
access to vector you can use vector::at(). With C++ very safe, =
bullef-proof
code can be written, simply by using the standard library facilities and
avoiding the use of low level stuff, direct memory =
allocation/deallocation,
casts, macros, void *s.

:) Java merely is a subset of C++ possibilites. Which is not necessarily

Myself I do not like Java (I am using the most soft words). There are =
many
reasons, but I do not want to begin a flame now. :) An interesting URL =

On the other hand I believe it is one of the worst (knowing at the same =

that there are many that disagree with me).

RE: Re[2]: [Dev-C++] [q] Does C++ promote bad programming?

[Per W. <pw...@ia...>]

It is very, very tough to write a C or C++ program without any pointers.

Try writing a hello world program :-)

I was about to supply one in this mail, when I realized that I couldn't
even get past main() without adding a pointer to any command line
arguments...

Re: [Dev-C++] Setting text colour

[Per W. <pw...@ia...>]

No, of course we know how to set colors for text output. It's just that
there is no STANDARD library functions for doing it. The conio package is
definitely not standard, so you can't just move your code to another
compiler and/or operating system and expect it to work.

We can hardly avoid knowing about the conio package since this list has
questions about it every 2-4 weeks.

Although that is the path I followed myself, C is not prerequisite for C++,
not to mention that they are very different languages right now. One can
learn procedural programming in C++ directly and more easily than in C by
using the standard library facilities.

Hello iad929 and all Dev-C++ users,

Avoiding pointers with C++ is hard thing, without dynamic storage and
dynamic object generation (long lasting) programs are not so
interesting... and what is more important C++ is hard becouse it mades
not boundary checking - it's because it aims for speed... and using
std::vector at an introductory course is neither good thing... at very
beginning you might be foced to answer what is std, namespace, vector,
template etc... this is all very confusing at the begining, and
without that people have many problems with programs in C++/C crushing
because some memory was written where it shouldn't - Java at first
such attempt stops! Which, for beginners to OOP is very important!
This forces good habbits as cerufully checking where last iterations
of loops will be writing to and many others... I'm talking here from
my point of view - my road to OOP was like this:
Basic (not even on PC class)
C
C++ and Java (at studies teachers somehow decided to combine these two)

and now I stick to C++ (with every aspect it offers - OOP, exceptions,
multithreading [this is more OS dependent, I know]) but I must say
that (for me) learning Java was a very good thing - at the time I
thought I shouldn't be doing that! I thought on high level programming

That's what I thing - IMO Java is very good start...

[Defiant H. <he...@er...>]

If you don't need to cover OOP, I'd suggest teaching plain C first.  It's 
much simpler, and this will help the students learn some of the nuances of 
the language before moving to C++.

Re: [Dev-C++] Setting text colour

[Louis G. <lg...@ya...>]

Damien,
Thank You, I compiled and ran your example under the DevC++ IDE. 
It works wery well. It seems that some of the DevC++ C experts
 are unaware of this.
I suspect you also know how to change fonts as well. An example of
this would also help many of us who are told this can't be done.

 Well Louis,

 I was surprised by so many people saying that it couldn't be done
anymore.
  The last time I did text colouring was last year. Anyway, this sample
works on my 
 system which is a P4 running WinXP.  It worked when I was runing WinME.  
 Tell me if It works on your system.


#include <conio.c>
#include <stdio.h>
#include <stdlib.h>

int main(void)
{
    printf("Hmmmm. Lets try to change these colors up.\n");
    textcolor(YELLOW);
    printf("This line should be blue\n");
    textcolor(RED);
    printf("This line should be red.\n");
    
    printf("Anyway. Later Guys\n");
    system("PAUSE");
    return 0;
}

Take a look at the conio.h header file in the Dev-C++ include directory. 
There are functions in there for console text formatting.  Make sure to
include the conio.c as an additional command while calling the compiler or
simple include it instead of conio.h.

C++ supports 4 paradigms:

- Procedural paradigm (functions)
- Modular paradigm (namespaces)
- Object Oriented paradigm
- Generic programming paradigm (templates)


Each paradigm is supported well (completely) with optimal space/time
efficiency.
