[Dev-C++] cin.get()

[patche <pa...@ro...>]

I am new to programming and have a huge story on all of the compiler/IDEs=
 that I've tried until I found DevCPP kudos to everyone involved.

There was a question that was asked about gett cin.get() to work.  I don't=
 know why but I had the same problem and the book with which I am teaching=
 myself or some other tutorial I was reading can't recall, suggested that I=
 use cin.get() twice, like so:

//template.cpp - Template for CPP

#include <iostream>
using namespace std;
int main()
{
     cin.get();
     cin.get();
     return 0;
}

So far, I haven't found any conflicts.  With what I know I will suggest=
 that the problem lies in the language itself.  I was studying the section=
 concerning strings and began to notice that the compiler actually hides=
 alot of useful stuff that would be good to know.  For instance, the=
 compiler will take a carriage return [ENTER] for a "\n" character and then=
 the newline character will be replaced with a null value "\0" of course=
 the "\0" represents yet another number. 

I don't know if the explanation helps but I am sure putting it in twice=
 will.

Thanks
Patche

There are 2 ways to do what you want the first requires you to

replace the cin.get();        with system("PAUSE");
N.B. To use system("PAUSE") you must include stdlib.h
The system is in common letters and the PAUSE is all capital
since you are learning I will include a snippet that does the exact
same thing

/* This does the same thing as system("PAUSE") */
cin.ignore(256, '\n');
cout << "Press ENTER to continue..." << endl;
cin.get();

The cin.ignore will keep reading from input and throwing it away until it
gets to '\n' (for your purposes the equivalent of the enter key) in other
word it flushes the buffer so the program will have nothing in the input
buffer when it gets to the cin.get and should wait
I have tested this in Dev-c++

[Dev-C++] Postgresql

[<ja...@xs...>]

Hi all..

I want to connect to a Postgresql database using devc++ (mingw) but I
can't seem to find the nescesary library.. does anyone know these
exist and where to find them? At the postgress site there is only the
complte download for a postgress install, but i need only the
client libs..

I found some pre-compiled lib/dll but the header-files are missing so
they are useless..

[Dev-C++] Prime number examples

[Mitchell, T. (HNA) <Tam...@hj...>]

Does any one have sample programs arrays and prime numbers?

I have a program Due Friday and am totally confused.

Can anyone point me in the right direction

Here is my exercise.

(The Sieve of Eratosthenes) A prime integer is any integer that is easily
divisible only by itself and 1. The Sieve of Eratosthenes is a method of
finding prime numbers.  It operates as follows
	a).  Create an array with all elements initialized to 1 (true).
Array elements with prime subscripts will remain 1.  All other array
elements will eventually be set to 	zero.
	
	b).  Starting with array subscript 2 (subscripts 1 must be prime),
every time an array element is found whose value is 1, loop through the
remainder of the array and 	set to zero every element whose subscript is
a multiple of the subscript for the element with value 1.  For array
subscript 2, all elements beyond 2 in the array that 	are multiples of 2
will be set to zero(subscripts 4, 6, 8, 10, etc.) for array subscript 3, all
elements beyond 3 in the array that a are multiples of 3 will be set to zero
(subscripts 6, 9, 12, 15 etc) and so on.

When this process is complete, the array elements that are still set to one
indicate that the subscript is a prime number.  These subscripts can then be
printed.  Write a program that uses an array of 1000 elements to determine
and print the prime numbers between 1 and 999.  Ignore element 0 of the
array.

 This is what I have so far

#include<iostream>

using std::cout;
using std::endl;

#include<iomanip>

int main()
{
	const int i[1000];
}

Not much.

Re: [Dev-C++] about debugging a C program

[<gi...@li...>]

Hello Javier,

I've tried the code that you posted with both the CLI version of gdb (I 
mean the one you get together with Dev-C++) and the GUI version (the one 
you used). I had no problem, the program worked as expected. So I can't 
tell you what is wrong.

There are a few things about your code, though, which I do not understand.

1. I see that you are worried about casting the value returned by some 
functions   (like "fprintf" or "fclose") to "void", even if you assign the 
return value to no variable.

2. The function "ckopen" is not supposed to modify the value of "name", but 
you use a "char*" instead of a "const char*". This also applies to the 
other argument and to the function "fatalf".

When I compiled your code the gcc compiler complained (i.e. issued a 
warning message) that "b.txt" is a "const char*" and you are passing it to 
a function ("ckopen") that expects a "char*".

3. You test for the ASCII character 0.

4. You test for the ASCII character 32 instead of the character literal ' '.

I have rearranged your code and am sending you the result, in the hope that 
it helps.

After the cin>>this number; the '\n' remains in the stream and is picked
by the next cin.get(). If you want to pause you must enter 2 cin.get():

#include <iostream>

int main()
{
 using namespace std;
  
 int thisisanumber;
 
 cout<<"Please enter a number:";
 cin>>thisisanumber;
 cin.get();
 
 cout<<"You entered: "<<thisisanumber;
 cin.get();

 return 0;
}

You forgot the semi-colon at the end of cin.get()

it should be cin.get();

Re: [Dev-C++] Dev C++ Question

[Jason S. <mys...@op...>]

Try using this,

#include <iostream.h>
int main()
{
  int thisisanumber;
  cout<<"Please enter a number:";
  cin>>thisisanumber;
  cout<<"You entered: "<<thisisanumber<<endl;
  cin.get()
  return 0;
}

I don't have access to any compilers at the moment, but I believe you need a endl or the such there...not quite sure though. :)

Hello...

I have a question about closing a terminal window during a C++ program 
execution.  I am using Dev C++ 4.01 as my compiler.  At 
http://www.cprogramming.com/close.html, it says that inserting the line 
cin.get() before the return 0 line will keep the terminal window open 
until I press enter.  This I find is true for the following program:

#include <iostream.h>
int main()
{
  cout<<"The Compiler Works";
  cin.get()
  return 0;
}


However for the following code, I type my number, press enter, and the window 
closes immediately.  Why doesn't the compiler display "You entered: ", then my 
number, and then close the terminal window once I push enter (which would be 
the second time)??  Am I putting the cin.get() statement in the wrong spot??
Check out the code I'm using.

#include <iostream.h>
int main()
{
  int thisisanumber;
  cout<<"Please enter a number:";
  cin>>thisisanumber;
  cout<<"You entered: "<<thisisanumber;

[Dev-C++] RE: Asm once again...

[<Ech...@ne...>]

I think that gcc uses AT&T(?) syntax, could it be that you are using intel syntax, and that the difference between the 2 is causing all the errors?

You might want to look at the "netwide asembler" (nasm) program it doesn't you GCC's syntax.  I think that if you use it then the asm would have to be in a different file, but I am not sure.  Actualy I've never used nasm, but I have hear it is gcc compatable and uses non gcc syntax

Something useful:
 
 
Recently, a report by IDC indicated that there are over 2.6 million
professional developers worldwide using C/C++ as their primary language
and over a million professional developers worldwide using Java as their
primary language. This means over 37% of all developers worldwide are
using these languages and the numbers continue to grow.

Tonight i have drunk a bit wine hic, but i just realised that the
original question was about some API. Anyway i made mistakes! in the
previous email in the C-style implementation so here is the correct one:

void *add(void *p1, void *p2, const char *type)
{
  if(!strcmp(type, "int"))
 {
   if(int *result=(int *)malloc(sizeof(int)))
  {
    *result=*(int *)p1+*(int *)p2;
     return result;
  }
 }

 else if(!strcmp(type, "float") 
 // Pain goes on...

}



And the template alternative is better written:

template <class T>
inline T add(const T &a, const T &b)
{
 return a+b;
}


Now if i made more mistakes, sorry fellows it is the wine. :)

In C++ a void * can not be assigned directly in any pointer type without
casting, e.g. the result of malloc() needs casting in C++. void * is
used a lot in C to emulate generic programming with poor abilities in
the particular area, that is to write functions that do things on
various types of variables using ancient non type safe techniques. C++
has built in support for generic programming with the best possible way,
templates. Templates arre both time efficient, space efficient if you
use specializations where is needed and type-safe at the same time. E.g.
consider the following C++ C-style code:

void *add(void *p1, void *p2, const char *type)
{
 if(strcmp(type, "int")
{
  if(int *resul=(char *)malloc(sizeof(int)))
 {
   *result=(int *)p1+(int *)p2;
    return result;
 }

 else if(strcmp(type, "float") 
 // Pain goes on...

}


Consider the template alternative:

template <class T>
inline T add(T a, T b)
{
 return a+b;
}


It is both type safe and maximally efficient.


So better use templates in the place where you use void * for generic
programming.

[Bob C. <rc...@ps...>]

Hi,
Here's a couple of suggestions:

Download MySQL and the MySQL C++ API from www.mysql.com.
The API has a manual and examples of working code.

Register at www.informit.com , go to the Free Library. There is a complete
online copy of the "Sams  Teach Yourself Database Programming with Visual
C++ 6 in 21 Days." It will give you enough material to apply the
code/concepts to other compilers and IDE's.

Bob

[Dev-C++] ANSI C++ forbids implicit conversion from `void *' in argument passing

[Flavio de S. <fla...@ne...>]

I am trying to compile a windows program and I am getting the following c=
ompiler error:

 ANSI C++ forbids implicit conversion from `void *' in argument passing

This error occurs two times in the following piece of code where I have t=
he value "0" (see below).

void WinClass::SetResIcons (int resId)
{
    _class.hIcon =3D reinterpret_cast<HICON> (
        ::LoadImage (
            _class.hInstance,=20
            MAKEINTRESOURCE (resId),=20
            IMAGE_ICON,=20
            ::GetSystemMetrics (SM_CXICON),
            ::GetSystemMetrics (SM_CYICON),
            0)); <-------------------------------------------------------=
-----------------------where i got the error
    // Small icon can be loaded from the same resource
    _class.hIconSm =3D reinterpret_cast<HICON> (
        ::LoadImage (
            _class.hInstance,=20
            MAKEINTRESOURCE (resId),=20
            IMAGE_ICON,=20

            ::GetSystemMetrics (SM_CYSMICON),
            0)); <-------------------------------------------------------=
-----------------------where i got the error

}

Does anyone know a possible cause? What should I do to compile it correct=
ly?

Please, help me.

If you want portability, only text is portable.That is it can be read in
all platforms. The catch is that text occupies more space.

In C or C++?

You will think a way. It depends on various factors, what searches you
will do, if you keep your records sorted ans by which criteria e.t.c..

I also suggest "The C++ Programming Language" 3rd Edition or Special
Edition by Bjarne Stroustrup the creator of C++.
