I'm not an expert myself - but maybe the compiler is treating 1000, 1000 &=20
100 as integers as there is no .0 involved? Maybe changing 1000 to 1000.0 an=
d=20
so on would resolve it? :-)

If not then back to the drawing board I'm afraid :-)

Peter,

There're weird thing with float numbers when you try to round or to use
the modulus division. If you use double instead of float you'll see
that the problem is over.

I don't know why but I had the same problem with a currency converter
program. Using (int p = 100 * (float) 0.65) was converted to int 64
whilst double 0.65 was converted to int 65.

Hope this helps

Chemanuel

In addition to Igor's comments, if you have a small test case that 
demonstrates the problems you are having, we can help you with 
that.

regards,

Nick

In your Program You tried (km_travelled%1000) I guess you wanted to find =
the remainder when km_travelled divided by 1000 The Modulus Operator % =
works only with integers.  If you want to find remainder use integer =
parsing. The Corrected Program Is Included Below....

#include <iostream.h>

void main()

{

     float ini_reading;
     float fin_reading;
     float km_travelled;
     float trav_cost;
     float wear_cost;

     // Title.
     cout << "Calculate the hire car cost. \n\n";

     // Ask for initial odometer reading.
     cout << "Please Enter the initial odometer reading :";
     cin >> ini_reading;

     // Ask for finial reading.
     cout << endl;
     cout << "Please Enter the finial odometer reading :";
     cin >> fin_reading;

     // Calculate costs.
     km_travelled =3D (fin_reading - ini_reading);
     trav_cost =3D (km_travelled * 0.3);
     wear_cost =3D ((km_travelled / 1000) - (((int)km_travelled % 1000) =
/ 100) *
200);

     // Display total hire car cost.
     cout << "The total hire car cost is $" << (wear_cost + trav_cost);
     cout << endl << endl;

     // Finish program.
     cin.ignore(1);
     cin.get();


}

Hi,

There may be some misunderstanding - Dev-C++ is
an IDE that uses GNU gcc/g++ as a compiler. As far
as I know gcc adheres to most of the ANSI/ISO
standards (there may be some incompatibilities).
What standard libraries & headers are you missing?
Of course Dev-C++ has many features for Windows
development but if you use them or not is up to you.

Regards

Igor Pierscinski

Normally you would use -I/usr/include -I/home/xwin/include -I. 
 
That is using a capital I not L. (-L is used to include libraries).

Hello,

Sorry for those who don't speak french

Je ne crois pas qu'il soit possible d'inclure de l'asm dans ton code
C/C++. Tu
peux utiliser un assembleur comme nasm (http://
http://www.web-sites.co.uk/nasm/),
qui peut produire des fichiers objets compatibles avec GCC, pour les
parties en
asm. Ensuite tu "link"  les fichiers objet (ceux de ton prog en C et
ceux du prog asm). Pour la marche à suivre voir la doc de nasm et celle
de gcc.

Don't rename the lib.
Don't link using -l linker options go to project options and put the path
and filename in extra include files section.
This might work (I hope - this is just what I do usually).
