All you have to do is adding the conio.c file to the list of your 
project source files and compile. The compilation will create the 
conio.o which you can use later instead.

Re: [Dev-C++] "const_cast" Help please.....

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

Remember one thing.

In the general case, it is impossible to convert a constant storage to a
non-constant storage.

You can cast away the const keyword, but that isn't the same as making the
const variable writeable - in some cases const variables are stored in
read-only memory - quite common for example for text strings, i.e. the
text "hello world" is often stored in the the application code (which is
write-protected). The alternative would require the compiler to copy the
text string from application code to a writeable variable on startup, i.e.
requiring the storage of the string in two different places.

Also, a lot of compilers treats const variables in a special way, i.e.
they really threat them as constants and not variables - similar to an
enum or #define.

So, if you do:

const int n = 20;
printf("%d",n);

the compiler knows that n is promised to always have the value 20. It may
then rewrite the printf() to:

printf("%d",20);

and obvisously, it doesn't matter if you manage to somehow change the
value of n - the compiler doesn't load n from any memory position but
instead uses the numeric value directly in following code.

[Dev-C++] "const_cast" Help please.....

[Farzan H. <far...@ho...>]

Hi users,

I've recently faced to some confusing results that "const_cast" makes.
Let's assume we have the following code:

const float i=3D55.5;
float * j=3Dconst_cast<float*>(&i);
cout << j << '\t' << &i << endl;  // Displays addresses.
*j=3D45.6;
cout << *j <<'\t' << i << endl;  // Displays contents.

If you run the code you will see something like this:
0x22ff78	0x22ff78
45.6	55.5

As you can see, the address of "i" is "0x22ff78" and it is the place wher=
e =20
"j" points to it.
The value of "i" is 55.5 but the value of the place where "j" points to i=
t =20
is 45.6!!
How can a single memory block store two different values????

Now there is another strange result. If you assign 45.6 to "j" immediatel=
y =20
after
"const_cast" (instead of assigning after displaying addresses) like this:

const float i=3D55.5;
float * j=3Dconst_cast<float*>(&i);
*j=3D45.6;
cout << j << '\t' << &i << endl;  // Displays addresses.
cout << *j <<'\t' << i << endl;  // Displays contents.

the result will be:
0x22ff78	0x22ff78
55.5	55.5

I should mention that this distinction is made when you use DEV-C++ 5.If =
=20
you use DEV-C++ 4,
only the first result will be produced for both codes.

I also tested the codes in MS Visual C++ 6 and it showed me the following=
 =20
result for both:
0012FF7C	0012FF7C
45.6	45.6

The value of "i" is 45.6 now. I think it is more acceptable result becaus=
e =20
by using
"const_cast", a constant storage (i) has been converted to a non constant=
 =20
storage (j)
and you can change its content.

Now please explain these results.
Thanks,

There are some serious errors in your code; you might want to read a 
book - or at least a good tutorial - on C programming.


>     while(!feof(col))


That's not the way to read a file. Unlike Pascal, in C (and in most of 
the existing languages) I/O functions can't predict the future; feof() 
will not tell you "in the future, when you try to read from this file, 
I'll find nothing to read"; instead, it tells you "last time you tried 
to read, I reached the end-of-file". See 
http://www.eskimo.com/~scs/C-faq/q12.2.html
What you need is to test the result of the function you used to access 
the file (e.g. fscanf() will return the number of successful assignments).

---
while (fscanf(col,"%f",&data.utl)  == 1)
{
         ...
}
---

>                fscanf(col,"%f\n",&data.utl);


Always avoid using a '\n' in *scanf() calls. See 
http://www.eskimo.com/~scs/C-faq/q12.17.html

For each read operation, you might also want to accumulate the value; 
initialize a variable before the while with zero, and add the read value 
to it:

---
float total = 0;

while (fscanf(col,"%f",&data.utl)  == 1) {

               total += data.utl;
}
---


>             fflush(stdin);


You shouldn't do this; See http://www.eskimo.com/~scs/C-faq/q12.26.html

There is a version without GCC also. Ensure that you have installed

I asked for help, rather than spend  hours searching google or finding just
the right book for the job, the nice coders here on the mailing list would
be happy to help me correct a simple mistake I made  and if you notice,
Verne, someone has. My problem is fixed, and I can progress in my learning,
and hopefully won't have to ask for help again. now, I've seen you help

RE: [Dev-C++] Couldn`t link MinGW DLL to MSVC program

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

One addendum.

The C++ standard requires name mangling, since the language support
multiple functions with the same name but different parameter signatures,
such as:
int add(int a,int b);
doule add(double a,double b);
Complex& add(Complex& a,Complex& b);

C compilers knows that functions already have unique names, so they can
ignore parameter count, parameter types etc.

However, some compilers can add extra name mangling to mark functions
compiled with non-compatible calling conventions. If you build one C
file with all functions taking the parameters in processor registers and a
second C file with all functions sent on the stack, a program would fail
if a function in one file calls a function in the other file. If the
compiler for example adds a $ at the end of the names of all functions
built with register calling convention, then the linker will automatically
fail to link such a program and you avoid creating a badly broken
application.

So in short - there _can_ exist C name mangling, but it is for a different
reason and it isn't because of parameter count/types but to detect
incompatible compiler optimization rules. Some of these compilers have
also added non-standard keywords to for example specify:

__regcall int add(int a,int b);

to inform that a specific function has a specific calling convention
different from the one used in the normal C libraries.

That is correct - no name mangling for C. But you may still get some extra
characters in the names. The normal is that you get a leading '_' for all
external C symbols but to my knowledge there exists environments where a
'$' first or last might be used. The leading '_' was added to place the C
symbols in their own "namespace" to avoid name collisions with operating
system symbols, i.e. open is a OS function while _open is the function
available in the C standard library and called by the C code.

Re: [Dev-C++] (no subject)

[jose i. c. <ji...@gm...>]

Jay,

wrong!  I do my own research, read my books and do my homework.=20
Though, I am been known to ask a question here and there.=20
Nonetheless, there is a difference between saying,

"The good way to start programming is by doing research on the
internet, books, newsgroup, etc.  What you are trying to do, many
other folks have already done.  So, i would suggest for you, "such and
such" book, by "such and such" author.  I also suggest www.cpp.org and
www.someothercpp.org and www.anotherwebsite.com has been extremely
helpful to me.  You may want to give those a try and when you get
stuck, come back and ask us.  We'll be here waiting.  By the way,
happy programming!"

and let the guy go with a bunch of knowledge and thinking that we are
nice people.  But putting the guy down like that it makes no sense.=20
You know, many people hate us c/c++ programmers because we are nasty.=20
Not because we are smart, which we are, but because we are nasty to
people and other programmers.  We love to show our wisdom and how
smart we are and how great and short our code is and how...  I guess
that comes with the geeky side of us, but friends, it's a bad
reputation we geeky people have, which we should change: we are
socially challenged.

Just a thought...

Back to programming...

RE: [Dev-C++] (no subject)

[<Mat...@Ve...>]

Verne is new at C++ too by his own admission; therefore I think he's
qualified to say this: he has just been reading books and teaching himself.
Verne's point is that reading a book really would help, so, from his point
of view, suggesting (however loudly) that Austin read a book is actually
giving help, not being unhelpful.

Sometimes the "tough love" approach to programming help is appropriate.
Apparently, Verne believes this is a case where "tough love" help is the
right kind.

As for whether it was needed, we are all adults here and I don't think it's
our responsibility to judge Verne. It's up to Verne to use his own best
judgment, and I don't think he would be the type of person who would use bad
judgment before he wrote something.

Correct me if I'm wrong on some of my points. I'm just trying to point out
what Verne might have been thinking when he dispensed the advice.

a simple search or go to a book store.

  Hi. I'm new to programming, and don't know all the terminology, so =
please go easy on me.

  I'm trying to figure out how to create a include file so I can use =
it's functions in my programs, by just including it.

  Here's my simple test program that didn't work in the least ^^=20

  __________________________________________________

  the program I tried to link to:

  #include<iostream>

  using namespace std;


  int subten(int num)
  {
  num -=3D 10;
  return num;
  }

  The program I tried to link to the above with:

  #include <iostream>
  #include "subten"
  using namespace std;

  main()
  {

  int a =3D 20;
  cout << a << endl;=20
  a=3Dsubten(a);
  cout << a;

  system("pause");
  }

  Ok, now please don't chew me out to bad for the mistakes that I made, =
and are common knowledge to everyone but me :p. thanks.
