C++ script

Look at this

Code:: #include <iostream>
#include <cmath>
int main ()
{
using namespace std;

double num1;
cout << "Pick your number.." << endl;
cin >> num1;
double num2;
num2 = sqrt(num1);
cout << "The sqaure root of " << num1 << " is " << num2 << endl;
system("pause");
return 0;
}

What this does is brings up a output and says "Pick your number" Then you insert a number and i mean any number, press enter, and it tells you the square root of that number EPIC.

Okay?

Is cmath a standard C++ library? I'm learning from a book I got, and it hasn't mentioned the libraries yet, though I haven't read too far into it yet :/

(laziness ftw :P)

Correct cmath is a library, and when you use it like that you can use any built in math function C++ provides

I doubt you would necessarily need C or C++. The only good thing about them is they take nearly no system resources compared to others, but they take a lot longer to write. C or C++ should only be used if you actually need those spare resources, which in most cases you don't. Well, you won't need it unless you hack often...

No C++ can be used to make files, 3D games, or even 2D games, but we don't need it for a site. What we need is PHP, HTML, XML, and CSS.

I feel like making my own math functions. I haven't made functions in C++ yet so syntax will probably be completely wrong:

public static decimal sqrt(int number) return decimal number^0.5;

:\ any good?

Not quite. You don't need public static because it's not a member of any class.
Also, decimal would be double.

The only problem is that you'd have to

Code:: #include <cmath>

to get the pow function. cmath also has the sqrt function built in, so making your own would be redundant. in C++, the ^ operator is used on a bitwise level, and represents XOR. I've seen an inverse sqrt done on a bitwise level, which is, I think, the only way to make it without redundancy.

Did you forget to mention XHTML? That's my favorite.

It's unusualy, but sometimes C++ IS used for websites.

Oh, I'm so used to C# that I added public static to it...
