Write a java program that use multiple arrays This is a simple array program which does not use an "external class & demo program" If you wish, you may break it down into methods, but that is not required. a. Set up 4 arrays which hold data about 6 items you want to sell: [make them up] int[ ] itemnum int[ ] quantity double[ ] price double[ ] sales b. Set up loops to load the itemnum, quantity and price arrays c. Set up another loop to calculate values for the sales array. [= price * quantity] d. Set up another loop to print the item number and sales amount for each transaction . e. Set up another loop to calculate the total sales of all 6 items f. print the total sales amount

Answer:

Explanation:

import java.util.Array;

public class Items{

public static void main (String {} args){

// a. Set up 4 arrays which hold data about 6 items you want to sell

int [] itemnum = new int[](1,2,3,4,5,6);

int [] quantity = new int[](500,200,350,100,270,300);

double [] price = new double [](10000, 50000,30000, 22000, 26000,100200);

double[] sales = new double [6];

//b. Set up loops to load the itemnum, quantity and price arrays

for(int I=0;I<6;I++)

{

System.out.println("Item "+itemnum[I]);

System.out.println("Item "+quantity[I]);

System.out.println("Item "+price[I]);

}

//c. Set up another loop to calculate values for the sales array.

for(int j=0;j<6;j++)

{

sales[j] = quantity[j] * price[j];

}

//d. Set up another loop to print the item number and sales amount for each transaction

for(int k=0;k<6;k++)

{

System.out.println("Item Number "+itemnum[k]);

System.out.println("Sales Amount "sales[k]);

}

//e. Set up another loop to calculate the total sales of all 6 items

double totalsales = 0;

for(int l=0;l<6;l++)

{

totalsales+=sales[l];

}

//f. print the total sales amount

System.out.print("Total Sales: "+totalsales);

}

}

Use the STL class vector to write a C function that returns true if there are two elements of the vector for which their product is odd, and returns false otherwise. Provide a formula on the number of scalar multiplications in terms of n, the size of the vector, to solve the problem in the best and worst cases. Describe the situations of getting the best and worst cases, give the samples of the input at each case and check if your formula works. What is the classification of the algorithm in the best and worst cases in terms of the Big-O notation

Answers

Answer:

Code is provided in the attachment form

Explanation:

Vector Multiplication code:

Vector_multiplication.c file contains C code.

See attachment no 1 attached below

Classification of Algorithm: For creating elements in vector c of size n, number of scalar  multiplications is equal to n. The size of original two vectors scales directly with the number of  operations. Hence, it is classified as O(n).

Which toplogy is common in these days? and justify atleast fivereason

Answers

Answer: Star topology is commonly used these days.

Explanation:

  • As, start topology is the reliable network topology because the failure of a central node or a node cable does not affect the remaining other nodes.
  • In star topology, if the computer fails you can still access your data by using backup folder in your private file or folder.  
  • In this network topology it is easy to find faults and correct it timely.
  • The start topology is cost effective and easy to maintain.  
  • We can also connect multiple communication channels.
