Write a program that asks the user to input an integer named numDoubles. Create a dynamic array that can store numDoubles double

Hitman42 [59]

Answer:

Answered in C++

#include <iostream>

using namespace std;

int main() {

int size;

cout<<"Length of array: ";

cin >> size;

double *numDoubles = new double[size];

double sum =0;

cout<<"Array Elements: ";

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

cin>>numDoubles[i];

sum += numDoubles[i];

}

delete [] numDoubles;

cout<<"Average: "<<sum/size;

return 0;

}

Explanation:

This line declares the size (or length) of the array

int size;

This line prompts the user for the array length

cout<<"Length of array: ";

This gets the input from the user

cin >> size;

This dynamically declares the array as of double datatype

double *numDoubles = new double[size];

This declares and initializes sum to 0

double sum =0;

This prompts the user for elements of the array

cout<<"Array Elements: ";

The following iteration gets input from the user and also calculates the sum of the array elements

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

cin>>numDoubles[i];

sum += numDoubles[i];

}

This deletes the array

delete [] myarray;

This calculates and prints the average of the array

cout<<"Average: "<<sum/size;

Write a Java program that reads two numbers from the console. Based on the example in the textbook, write five methods (min, max

makvit [3.9K]

Answer:

import java.util.Scanner;

public class num6 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter first number");

int a = in.nextInt();

System.out.println("Enter second number");

int b = in.nextInt();

//Calling the methods inside the output statement

System.out.println("Min is "+min(a,b));

System.out.println("Max is "+ max(a,b));

System.out.println("Sum is "+sum(a,b));

System.out.println("Product is "+product(a,b));

System.out.println("Absolute difference is "+difference(a,b));

}

//Min Method

static int min(int a, int b){

if (a<b){

return a;

}

else {

return b;

}

//Max Method

static int max(int a, int b){

if (a>b){

return a;

}

else {

return b;

}

//Sum Method

static int sum(int a, int b){

return a+b;

}

//Diference Method

static int difference(int a, int b){

int diff = Math.abs(a-b);

return diff;

}

//Product Method

static int product(int a, int b){

int prod = a*b;

return prod;

}

Explanation:

Using Java programming language
Use the scanner class to prompt and receive two values from the user (integers a and b)
Create the four methods as required (Please see the comments in the code)
In the difference method use Math.abs() to get the absolute value of the subtraction ensuring that you get a positive number returned
