#include "cmath.h"

it's givin error about cmath.h...but why?!?

Code:

---

// troll1.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "iostream.h"
#include "cmath.h"

using namespace std;

void main()
{
        int cateto1, cateto2;
        cout << "Calcular a hipotenusa de um um triângulo sendo dados os seus catetos:\nCateto 1: ";
        cin >> cateto1;
        cout << "Cateto 2: ";
        cin >> cateto2;
        count << "A hipotenusa é" << hipotenusa(cateto1, cateto2);
}

int hipotenusa(int cateto1, int cateto2)
{
        cateto1 = cateto1^2;
        cateto2 = cateto2^2;

        return sqtr(cateto1 + cateto2);
}

maybe math.h?
squareroot is sqrt() not sqtr(), power is pow() although you can get away with cateto1*cateto1 resp..

no the problem is cmath...what should i do?

...

cmath.h doesn't exist. math.h is the C-header, cmath is the C++ version. cmath.h is nothing.
As parksie wrote, and don't forget that everything is in the std namespace.

but my vc6++ compiler doesnt allow the include's without the extension!

omg tryed with math.h and worked...but shouldnt be this have a cmath.h? u said the C has math.h and c++ has cmath.h..

No. It's math.h and cmath. No extension.

but if i put without extension i get error in the compiler!

damn im getting mad so many differences between what the book says and what i must do with vc6++...is borland's c++ best?

Visual C++ 6 supports cmath. At least it *should*, since v5 did. Personally, I think Microsoft's compiler absolutely trashes Borland's.

but mine didnt...i think ill ask to some friend for his cd to see if theres any difference or somewhat :\

Even my introductory edition of VC++6 supported <cmath>. And that's the smallest edition you can get (it was free).

Are you using:

Code:

---

#include <cmath>

---

or...

Code:

---

#include "cmath"

---

It shouldn't matter - but it might...

I can't see why cmath wouldn't work - works fine for me on VC++ 6.

HD

tryed the two ways right now and none of the works..just works with " " s and extension..maybe that's happening beacuse this is a riped version or something like that :confused:

What error do you get than? And you're sure your including
using namespace std also? Also make sure the include paths of your compiler are right.

where should they point to?

<vc++maindir>\include

yea it has math.h...but its confusing..because this should have cmath....bah
