Ivor.Hortons.Beginning.Visual.CPlusPlus.2010-indefinitely Loops issue

Issue: indefinitely loops can’t apply to 1.0 but for 0.6

Page 150:

for(double x = 0.0 ; x != 1.0 ; x += 0.2)        
	cout < < x;

Code should be updated as the following:

// Ex3_13.cpp
// Demonstrating nested loops to compute factorials
#include "stdafx.h"
#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
	cout.precision(21);
	for(double x = 0.0 ; x != 0.6 ; x += 0.2)
		//for(double x = 0.0 ; x != 1.0 ; x += 0.2)
	{
		if( 0.2 == x)
			cout << "0.2" << endl;
		if( 2 == x)
			cout << "2" << endl;
		if( 0.4 == x)
			cout << "0.4" << endl;
		if( 0.6 == x)
			cout << "0.6" << endl;
		if(0.8 == x)
			cout << "0.8" << endl;
		if(1.0 == x)
			cout << "1.0" << endl;
		if(1 == x)
			cout << "1" << endl;

		cout << fixed << x << endl;
	}
	return 0;
