Locker doors There are n lockers in a hallway, numbered sequentially from 1 to n. Initially, all the locker doors are closed. Yo
kow [346]

Answer:

// here is code in C++

#include <bits/stdc++.h>

using namespace std;

// main function

int main()

{

   // variables

   int n,no_open=0;

   cout<<"enter the number of lockers:";

   // read the number of lockers

   cin>>n;

   // initialize all lockers with 0, 0 for locked and 1 for open

   int lock[n]={};

   // toggle the locks

   // in each pass toggle every ith lock

   // if open close it and vice versa

   for(int i=1;i<=n;i++)

   {

       for(int a=0;a<n;a++)

       {

           if((a+1)%i==0)

           {

               if(lock[a]==0)

               lock[a]=1;

               else if(lock[a]==1)

               lock[a]=0;

           }

       }

   }

   cout<<"After last pass status of all locks:"<<endl;

   // print the status of all locks

   for(int x=0;x<n;x++)

   {

       if(lock[x]==0)

       {

           cout<<"lock "<<x+1<<" is close."<<endl;

       }

       else if(lock[x]==1)

       {

           cout<<"lock "<<x+1<<" is open."<<endl;

           // count the open locks

           no_open++;

       }

   }

   // print the open locks

   cout<<"total open locks are :"<<no_open<<endl;

return 0;

}

Explanation:

First read the number of lockers from user.Create an array of size n, and make all the locks closed.Then run a for loop to toggle locks.In pass i, toggle every ith lock.If lock is open then close it and vice versa.After the last pass print the status of each lock and print count of open locks.

Output:

enter the number of lockers:9

After last pass status of all locks:

lock 1 is open.

lock 2 is close.

lock 3 is close.

lock 4 is open.

lock 5 is close.

lock 6 is close.

lock 7 is close.

lock 8 is close.

lock 9 is open.

total open locks are :3

4.2: Roman Numeral Converter Write a program that asks the user to enter a number within the range of 1 through 10. Use a switch
Reptile [31]

Answer:

The solution code is written in Java

  1. import java.util.Scanner;
  2. public class Main {
  3.    public static void main (String [] args) {
  4.        Scanner inStream = new Scanner(System.in);
  5.        System.out.print("Please input a number (1 - 10): ");
  6.        int num = inStream.nextInt();
  7.        if(num < 1 || num > 10){
  8.            System.out.println("The input must be between 1 - 10");
  9.        }else{
  10.            switch(num){
  11.                case 1:
  12.                    System.out.println("I");
  13.                    break;
  14.                case 2:
  15.                    System.out.println("II");
  16.                    break;
  17.                case 3:
  18.                    System.out.println("III");
  19.                    break;
  20.                case 4:
  21.                    System.out.println("IV");
  22.                    break;
  23.                case 5:
  24.                    System.out.println("V");
  25.                    break;
  26.                case 6:
  27.                    System.out.println("VI");
  28.                    break;
  29.                case 7:
  30.                    System.out.println("VII");
  31.                    break;
  32.                case 8:
  33.                    System.out.println("VIII");
  34.                    break;
  35.                case 9:
  36.                    System.out.println("IX");
  37.                    break;
  38.                case 10:
  39.                    System.out.println("X");
  40.                    break;
  41.            }
  42.        }
  43.    }
  44. }

Explanation:

The first part of this program (Line 6 - 8) is to get input number from user using Scanner object. Input validation has been done to check if the input number is in the acceptable range (Line 10). If not, an error message will be displayed (Line 11).

If the input number is in the range of 1 - 10, the number will go through a series of switch statements checking. If the number meet the condition in one of the switch cases, it will print the corresponding roman numeral specified in the case block (Line 13 - 44). For example, if input number is 9, the case 9 condition is met and "IX" will be printed.
