[LF Help] Calculator

[P1raten]

Im looking for a way to calculate something like this in cpp:
x = √y * z

heres a part of my script so that you can make the 'fix' compatible.

           case '2':
		cout<<"\n";
                cout<<"Write the amount of Resistance..\n";
                cin>>num;
                cout<<"Write the amount of Current..\n";
                cin>>num2;
                cout<<num * num2;
                cout<<"\n";
		cout<<"\n";
                break;

#include <math>

double sqrt(double);
float sqrtf(float);

// ...

float result = sqrtf( num * num2 );
cout << "The square root of " << num << " * " << num2 << " is " << result << "." << endl;

I get the error:
Error 1 fatal error C1083: Cannot open include file: 'math': No such file or directory c:\documents and settings\klr9lijuhli\mina dokument\visual studio 2005\projects\answerer\answerer\main.cpp 3

#include <math>

double sqrt(double);
float sqrtf(float);


case '1':
cout<<"\n";
cout<<"Write the amount of Resistance..\n";
cin>>num;
cout<<"Write the amount of Effect..\n";
cin>>num2;
cout<<sqrtf(num * num2);
cout<<"\n";
cout<<"\n";
break;

Here's the full script:

math.h ._.

Do me a favor and dont use that ****ing bad style. Also: '1' is not 1.

[MaiN]

Also: '1' is not 1.

He's checking for the entered key.

[P1raten]

I still get the error. And i got the math.h in the same directory as the main.cpp

EDIT: Nvm i fixed it. Thx schlumpf

[schlumpf]

He's checking for the entered key.

Looking at the last "calculator" topic, people seem to use cin and an integer for such things. I didn't think he would take a char.

Also, I love the "case '11':" part.

math.h ._.

Not "math.h". "cmath".

[schlumpf]

Not "math.h". "cmath".

Oh right, we are in ++.. I get confused by my terrible C lecture. God, I wish I wouldn't be forced to attend it. That's what you get for wanting a bachelor's degree. ._.

[P1raten]

Not "math.h". "cmath".

If i just make a file named math.h and write:

#include "math.h"

in main.cpp

then it works.

Failure.

If i just make a file named math.h and write:

#include "math.h"

in main.cpp

then it works.
