Write a program that performs the following tasks: Display a friendly greeting to the user Prompt the user for the value to conv

ert (a String) Accept that String Prompt the user for the value of the initial base (an integer) Accept that integer Prompt the user for the desired base of the output (an integer) Accept that integer If the String is not a legal expression of a number in the initial base, display an error message and exit the program. Convert the value represented by the String in the initial base to the desired base. Display the result.

Explanation:

import java.util.Scanner;

import java.math.BigInteger;

public class Main

{

private int x;  

public static boolean isValidInteger(String theValue, int theBase)

{    

BigInteger number = new BigInteger(theValue,theBase);

if(theValue.equals(number.toString(theBase)))

{

return true;

}

else

return false;

}

public static String convertInteger(String theValue, int initialBase, int finalBase)

{

boolean valid=isValidInteger(theValue,initialBase);

if(valid==true)

{

BigInteger number = new BigInteger(theValue);

return(number.toString(finalBase));

}

else

return("String not in initial base");  

}

public static void main(String[] args)

{

System.out.println("Welcome");

String value;

int ibase, dbase;

if(args.length==0)

{

Scanner S = new Scanner(System.in);

System.out.println("Enter Value to be converted :: ");

value = S.nextLine();

System.out.println("Enter initial base :: ");

ibase = S.nextInt();

System.out.println("Enter desired base :: ");

dbase = S.nextInt();

}

else

{

value=args[0];

ibase=Integer.parseInt(args[1]);

dbase=Integer.parseInt(args[2]);

}

  System.out.println("Change base "+convertInteger(value,ibase,dbase));  

}

}

Briefly define each components of information systems (hardware, software, data, networking, people and procedure). While you ar
WARRIOR [948]

Answer:

1. Hardware is the physical components that compose a system and provide physical quantity and quality to software applications and accomplish information processing tasks

2. Software is a program that carries out a set of instructions written in a programming language. It instructs a computer on how to carry out specific tasks. Programs can be saved permanently or temporarily.

3. Data may be mostly the raw resources used by information systems experts to give business intelligence to users. Traditional alphanumeric data, which is made up of numbers and alphabetical and other characters, is one type of data.

4. Networking is a resource of any computer system connected to other systems via a communications. It refers to the physical connections between all of the network's nodes. Communication networks are a critical resource component of all information systems, according to networking.

5. People are those who are directly or indirectly involved in the system. Direct users include developers, programmers, designers, and system administrators. Direct users can also be the stakeholder or end user who receives an output from the system. Indirect can be a manager who takes a brief check at the system to check that all criteria are satisfied.

6. Procedure is made up of stages or phases that result in an output. A method of continually receiving feedback on each part while analyzing the overall system by observing various inputs being processed or altered to create outputs.

Write a C console application that will be used to determine if rectangular packages can fit inside one of a set of spheres. You
MatroZZZ [7]

Answer:

#include <cmath>

#include <iostream>

using namespace std;

int getSphereSize(double length, double breadth, double height) {

   double diagonal = sqrt(length * length + breadth * breadth + height * height);

   if (diagonal <= 4)

       return 4;

   if (diagonal <= 6)

       return 6;

   if (diagonal <= 8)

       return 8;

   if (diagonal <= 10)

       return 10;

   if (diagonal <= 12)

       return 12;

   return 0;

}

int main() {

   double length, breadth, height;

   int sphereCounts[5] = {0};

   int sphereSize;

   while (true) {

       // Get dimensions of the box

       cout << "Enter the dimensions of the box:\n";

       cout << "Length: ";

       cin >> length;

       cout << "Breadth: ";

       cin >> breadth;

       cout << "Height: ";

       cin >> height;

       if (length <= 0 || breadth <= 0 || height <= 0)

           break;

       sphereSize = getSphereSize(length, breadth, height);

       if (sphereSize == 0)

           cout << "The box cannot fit in any of the spheres";

       else

           cout << "The box can fit in the " << sphereSize << "-inch sphere";

       // Increment the counter

       if (sphereSize == 4)

           sphereCounts[0]++;

       else if (sphereSize == 6)

           sphereCounts[1]++;

       else if (sphereSize == 8)

           sphereCounts[2]++;

       else if (sphereSize == 10)

           sphereCounts[3]++;

       else if (sphereSize == 12)

           sphereCounts[4]++;

       cout << "\n\n";

   }

   cout << "\nNumber of 4-inch spheres: " << sphereCounts[0];

   cout << "\nNumber of 6-inch spheres: " << sphereCounts[1];

   cout << "\nNumber of 8-inch spheres: " << sphereCounts[2];

   cout << "\nNumber of 10-inch spheres: " << sphereCounts[3];

   cout << "\nNumber of 12-inch spheres: " << sphereCounts[4];

   cout << endl;

   return 0;

}

Explanation:

The "cmath" library is included in the c++ program. The getSphereSize function is used to return the sphere size the rectangle dimension can fit into. It program continuously prompts the user for the length, breadth, and height of the rectangle and passes the values to the getSphereSize function in the while but breaks if any or all of the variable value is zero.

The sizes of the sphere objects in inches are collected in an array of five integer values of zeros and are incremented by one for every match with a rectangle.
