Given the availability of an ifstream object named input, write the other statements necessary to read an integer into a variabl

tatiyna

Answer:

input.open("rawdata");

input>>datum;

input.close();

Explanation:

ifstream objects maintain a filebuf object as their internal stream buffer, and perform operations like input/output on the available associated files.

In above statements.

input.open("rawdata");

The associated file named rawdata is opened.

input>>datum;

The integer from the file is read into already declared variable datum.

input.close();

Input stream is closed.

You have installed a streaming video service on your network. You want selected hosts to be able to access this service via a dy

vitfil [10]

You can add the MAC addresses of hosts that you want to allow the access in a database, if you are working on a large scale, and then compare the MAC address of the user in you network wall and allow th users that are allowed.

Or if you are working on a small scale then in your program you can save the MAC in an array or model class and compare when the user will access.

Variance for accumulator. Validate that the following code, which adds the

Art [367]

Using the knowledge of computational language in JAVA it is possible to write a code that Validate that the following code, which adds the methods var() and stddev() to Accumulator, computes both the mean and variance of the numbers presented as arguments to addDataValue()

<h3>Writting the code:</h3>

import java.util.*;

public class Accumulator {

private static double m;

private static double v;

private static double st;

private static double s[]=new double[5];

private static int N;

private static int count =0;

public static void main(String[] args) {

// TODO Auto-generated method stub

Random r = new Random();

System.out.println("hello world");

for(int i=0;i<5;i++) {

double randomvalue = r.nextDouble();

addDataValue(randomvalue);

}

for(int i=0;i<s.length;i++) {

System.out.println("dataValue:"+s[i]);

}

mean();

System.out.println("mean:"+m);

var();

System.out.println("variance:"+v);

stddev();

System.out.println("standard deviation:"+st);

}

public static void addDataValue(double value) { // addes data values to array

s[count]=value;

count++;

}

public static double mean() { // returns mean

double sum=0.0;

for(int i=0;i<s.length;i++) {

sum+=s[i];

}

m = sum/s.length;

return m;

}

public static double var() { //returns variance

double mm = mean();

double t = 0;

for(int i=0;i<s.length;i++) {

t+= (s[i]-mm)*(s[i]-mm);

}

v= t/(s.length-1);

return v;

}

public static double stddev() { // returnsn the stardard deviation

st= Math.sqrt(var());

return st;

}
