Write a program that prompts the user to enter positive integers (as many as the user enters) from standard input and prints out

julia-pushkina [17]

Answer:

Here is the JAVA program that prompts the user to enter positive integers from standard input and prints out the maximum and minimum values:

import java.util.*;

public class Ex0603 {

public static void main(String[] args) { //start of main function

Scanner in = new Scanner(System.in); //creates Scanner class object to take input from user

int minimum = 0; //stores the minimum of the integers

int maximum = 0; //stores the minimum of the integers

int num; //stores the positive integer values

System.out.println("enter a positive integer: ");//prompts user to enter a positive integer

num = in.nextInt();//scans and reads the input integer value from user

minimum = num; //assigns value of num to minimum

while(true) {//while loop keeps prompting user to enter a positive integer

System.out.println("enter a positive integer: ");//prompts user to enter a positive integer

num = in.nextInt();//scans and reads the input integer value from user

if(num <=0)//if the user inputs a negative integer or 0

break; //breaks the loop

if (num > maximum) {//if the value of positive integer is greater than the maximum of value

maximum = num; } //assigns that maximum value of num to maximum variable

if (num < minimum) {//if the value of positive integer is less than the minimum of value

minimum = num; //assigns that minimum value of num to minimum } }

System.out.println("The maximum integer is : " + maximum); //displays the maximum of the positive integers

System.out.println("The minimum integer is : " + minimum); }} //displays the minimum of the positive integers

Explanation:

Here is the JAVA program that that prompts the user to enter an integer N, then reads N double values, and prints their mean (average value) and sample standard deviation:

import java.util.*;

public class Ex0603 {

public static void main(String[] args) { //start of main function

Scanner in = new Scanner(System.in); //creates Scanner class object to take input from user

double integer= 0; //to store the number of input values

double sum = 0; //to store the sum of input numbers

double mean = 0; //to store the average of numbers

double sd = 0; //to store the standard deviation result

double variance = 0; //to store the variance result

double sumSquare = 0; //to store the sum of (num-mean)^2

int n = 0; //to store the sample size N

System.out.println("Enter an integer: "); //prompts user to enter an integer that is how many elements user wants to input

integer = in.nextInt(); //reads the value of integer from user

double size=integer; // declares a double type variable and assigns value of int type variable integer to this double type variable size

int i=0; //used to point each element of the num array

double num[] = new double[(int)size]; //declares an array to hold the numbers input by user

while(integer>0){ //loop executes until value of integer is greater than 0

System.out.println("Enter a number: "); // prompts to enter a number

num[i] = in.nextDouble(); //reads double values

sum += num[i]; //adds the values stored in num array

i++; //increments i to point to the next element in num array

n++; //increments n to count the total number of elements

integer--; //decrements integer value at each iteration

mean = sum / n; } //compute the average of values

i=0;

while(size>0){ //loop executes until value of size exceeds 0

sumSquare += Math.pow(num[i]-mean,2); //takes the sum of square difference between each element of num array and value of mean

i++; //increments i

size--; } //decrements size

variance = sumSquare / (n-1); //compute variance by dividing the result of sum of the squares of their differences from the mean by n-1

sd = Math.sqrt(variance); //computes standard deviation by using sqrt function which takes the sqrt of the result of variance computed above

System.out.println("Average value is: " + mean+ " and the standard deviation is " + String. format("%.2f", sd)); }} //displays the average of numbers stored in mean variable and value of standard deviation is displayed up to 2 decimal places

Screenshots of both programs and their outputs is attached.

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;

}

This variable controls the number of times that the loop iterates. A. Counter variable B. Loop control variable C. Running total

Norma-Jean [14]

Answer:

B) Loop control Variable

Explanation:

When programming, A loop control variable is used to control the number of iterations for a program loop. By convention programmers love to call this variable counter, i, j, n etc. The control variable when defined will determine the number of times a loop will execute. See the example bellow in C++ where we use a for loop to print the word "Hello" 5 times

#include <iostream>

using namespace std;

int main()

{

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

cout<<"Hello"<<endl;

}

return 0;

}

In this code snippet, the control variable is called counter and the condition is that counter will run from 0 to 4. So we get the world Hello printed five times
