Hello,

I have an assignment to convert some given jave code into c++. I am currently having an issue wherein when I run the program it tells me that: error C2660: 'approximateSqrt' : function does not take 1 arguments. Any suggestions for moving forward would be appreciated. I have the following:

```
#include <iostream>
#include <iomanip>
#include <string>
#include <cmath>
using namespace std;
// Function Prototyping
double getValue();
double getInitialGuess();
double approximateSqrt();
int main()
{
double x = getValue();
double xSqrt = approximateSqrt(x);
cout<<"\nsqrt( %1.6f ) = %1.6f\n", x, xSqrt ;
}
// FUNCTION 1
double getValue()
{
double value;
cout<<"Enter value (>0) whose square root will be computed: ";
cin>>value;
while ( value <= 0 )
{
cout<<"Invalid value "<<value<<" <= 0" ;
cout<<endl<<" -- try again";
cout<<endl<<"Enter value (>0): ";
cin>>value;
}
return value;
}
// FUNCTION 2
double getInitialGuess( double value )
{
return value / 2.0;
}
// FUNCTION 3
double approximateSqrt( double value )
{
double epsilon = 0.00001;
double x = getInitialGuess( value );
//System.out.printf( "sqrt( %1.6f ) = %1.6f\n", value, x );
cout<<"sqrt( %1.6f ) = %1.6f\n", value, x;
// SOMETHING TO DO WITH CMATH
while ( abs( value - x * x ) > epsilon )
{
double tx = x;
x = 0.5 * ( x + ( value / x ) );
//System.out.printf( "sqrt( %1.6f ) = 0.5 * ( %1.6f + ( %1.6f / %1.6f ) ) = %1.6f\n", value, tx, value, tx, x );
cout<<"sqrt( %1.6f ) = 0.5 * ( %1.6f + ( %1.6f / %1.6f ) ) = %1.6f\n", value, tx, value, tx, x;
}
return x;
}
```
