#include "cmath.h"

**PT Exorcist** · Dec 17th, 2002, 08:06 AM

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.

**PT Exorcist** · Dec 18th, 2002, 08:03 AM

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

**PT Exorcist** · Dec 18th, 2002, 08:05 AM

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..

**parksie** · Dec 18th, 2002, 08:13 AM

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

**PT Exorcist** · Dec 18th, 2002, 08:18 AM

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

**PT Exorcist** · Dec 18th, 2002, 08:19 AM

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

**parksie** · Dec 18th, 2002, 08:31 AM

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

**PT Exorcist** · Dec 18th, 2002, 08:33 AM

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

**CornedBee** · Dec 18th, 2002, 08:41 AM

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

**HairyDave** · Dec 18th, 2002, 08:47 AM

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.

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

**Jop** · Dec 18th, 2002, 12:00 PM

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.

**PT Exorcist** · Dec 18th, 2002, 01:52 PM

where should they point to?

**CornedBee** · Dec 18th, 2002, 05:04 PM

<vc++maindir>\include

**PT Exorcist** · Dec 18th, 2002, 08:57 PM

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