Errors in Code

[TommyGun4]

There are errors in my code at lines 37 and 40 and i'm not sure how to fix them/ what I did wrong

#include <fstream>
#include <iostream>
#include <math.h>
#include <stdlib.h>
#include <iomanip>

using namespace std;

int main(void)
{
	double epsilon = .00000001, a, b, i, x0, x1;
	char zzz;
	const char filepath[] = "C:\\CoutputFiles\\File3.txt";
	const char ErrorMessage[] = "Can't open file ";
	fstream OutStream(filepath, ios::out);
	if (OutStream.fail())
	{
		cerr << ErrorMessage << filepath;
		cin >> zzz;
		exit(-1);
	}

	cout << "Program will approximate the square root of a number + 40\n\n";
	cout << "Type in the last 2 digits of your University X number:\n";
	cin >> a;
	b = a + 40;
	cout << "\nYou entered: " << a;
	OutStream << "You entered: " << a << "\n";
	cout << "\nFinding the square root of " << b;
	cout << "\n\nList of steps with approximations: ";
	if (a < 0.0);
	system("pause");
	{
		cout << "Cannot find square root of a negative number...";
	}
	{
	else (int i = 1);
	x0 = b;
	x1 = (x0 + b / x0) / 2;
	while (fabs(x1 - x0)) > epsilon)

	{
	(x0 = x1;);
	x1 = (x0 + b / x0) / 2;
	cout << "\nStep " << i << ": " << x1;
	OutStream << i << ", " << x1 << ", ";
	i++;
	}
	cout << "\nThe square root of " << b << "is " << x1;
	OutStream << "\nThe square root of " << b << "is " << x1;
	}
	OutStream.close();
	cout << "\nPress any character then 'Enter'...";
	cin >> zzz;
	return 0;
}

i think this:

invert line 32 with line 33 and delete semicolon at end of line 31;
delete line 41 ;

also a brace between those present in the lines 36 or 48 or 51 , it is useless

I just updated the code but it still doesn't work

#include <fstream>
#include <iostream>
#include <math.h>
#include <stdlib.h>
#include <iomanip>

using namespace std;

int main(void)
{
	double epsilon = .00000001, a, b, i, x0, x1;
	char zzz;
	const char filepath[] = "C:\\CoutputFiles\\File3.txt";
	const char ErrorMessage[] = "Can't open file ";
	fstream OutStream(filepath, ios::out);
	if (OutStream.fail())
	{
		cerr << ErrorMessage << filepath;
		cin >> zzz;
		exit(-1);
	}

	cout << "Program will approximate the square root of a number + 40\n\n";
	cout << "Type in the last 2 digits of your University X number:\n";
	cin >> a;
	b = a + 40;
	cout << "\nYou entered: " << a;
	OutStream << "You entered: " << a << "\n";
	cout << "\nFinding the square root of " << b;
	cout << "\n\nList of steps with approximations: ";
	if (a < 0.0)
	
	{
		cout << "Cannot find square root of a negative number...";
	}
	else (int i = 1);
	x0 = b;
	x1 = (x0 + b / x0) / 2;
	while (fabs(x1 - x0)) > epsilon)

	{
	(x0 = x1;);
	x1 = (x0 + b / x0) / 2;
	cout << "\nStep " << i << ": " << x1;
	OutStream << i << ", " << x1 << ", ";
	i++;
	}

	cout << "\nThe square root of " << b << "is " << x1;
	OutStream << "\nThe square root of " << b << "is " << x1;
	OutStream.close();
	cout << "\nPress any character then 'Enter'...";
	cin >> zzz;
	return 0;
}

On line 36 it says - expected a ')' & expected an expression
On line 39 it says - expected an expression underlining the ">"
