2.0e1.0 to 20.0

need help converting an outputed double from 2.0e1.0 to 20.0!!!
on a mac it would simply be cout << ... << fixed << showpoint << setprecision(1) << 20;
but when i do that in VC++ it tells me fixed and showpoint are unidentified identifiers

plz help!!!

thanks!!

here's a sample of code that doesnt work:

#include <iostream.h>
#include <iomanip.h>

int main() {
cout << fixed << showpoint << setprecision(2) << 200;
return 0;
}

VC++ will give me a compiling error of:
fixed unidentified identifier
showpoint unidentified identifier

but then if i do:

cout << setprecision(2) << 200;

it will output:

2.0e+2

how can i make it so it outputs:

200.00

?

thanks in advance!!

Code:

---

using System;

class DoubleOut
{
        public static void Main()
        {
                double x = 2.0e2;

                Console.WriteLine("Number equals "+x);
        }
}

One version with C#

Maybe go with C on this:
double num = 2e2;

printf("Number is %.2lf", num);

use the new headers instead of the old so...

#include<iostream>
#include<iomanip>
using namespace std;
.
