Explanation:
//Remove this header file if not using visual studio.
#include "stdafx.h"
//Include the required header files.
#include <iostream>
//Use for maths function.
#include <cmath>
using namespace std;
//Define main function
int main()
{
// Define the variables
double targetValue = 0.3333;
double sensorReading = 0.0;
//Perform the opeartion.
sensorReading = 1.0 / 3.0;
// Get the absolute floating point value and
// Check up to 4 digits.
if (fabs(sensorReading - targetValue) < 1E-4)
{
//Print equal if the values are close enough.
cout << "Equal" << endl;
}
else
{
//Print not equal if the values are not
//close enough.
cout << "Not equal" << endl;
}
system("pause");
//Return the value 0.
return 0;
}

Explanation:
Freeware and shareware programs are softwares which are either free of charge or consist of a free version for a certain trial period. These programs pose a threat of habouring malware or viruses which could damage one's computer and important files and programs. Therefore, it is imperative that carefulness is maintained when trying to get these softwares.
Some of the necessary safety conditions that should be taken include;
1) Appropriate research about the software including taking more about the vendors and reviews.
2.) Once, a healthy review has been identified ; the download can begin with the Downloader ensuring that the download is from the recommended site.
3) Prior to installation the software should be scanned with an active anti-virus program to determine if there is possibility that a virus has creeped in.
4.) Some softwares may require that computer anti-virus be turned off during installation, this is not always a good idea as this act leaves the system vulnerable a d badly exposed.
Errors in compilation happen, or it runs but then doesn't recognize the input. Also you can't transform into other types of variables.
Answer:
FF-FF-FF-FF-FF-FF and 255.255.255.255
Explanation:
FF-FF-FF-FF-FF-FF can be defined as the layer 2 address broadcast which is often used on ethernet frames as well as help to broadcast all equipment due to the fact broadcast is made possible through Ethernet networks in which the Frames are addressed to reach every computer system on a given LAN segment as far as they are addressed to MAC address FF:FF:FF:FF:FF:FF.
255.255. 255.255 can be seen as the layer 3 address which help to address the exact same hosts because it enables the broadcast address of the zero network which is the local network due to the fact that the IP broadcasts are often used by BOOTP and DHCP clients to find and send requests to their respective servers in which a message sent to a broadcast address may be received by all network-attached hosts.
Therefore the Layer 2 and Layer 3 destination addresses which the message contain are FF-FF-FF-FF-FF-FF and 255.255.255.255
