Write a program to simulate Sequential (Contiguous) file allocation method. Assume disk with n number of blocks. Give value of n as input. Write menu driver program with menu options as mentioned above and implement each option.

 


#include<stdio.h>
#include<string.h>

int n,m,i,j,k,flag;
int a[50][50],av[15],max[50][50],need[50][50];

void get_data()
{
     printf("\nEnter number of processes : ");
     scanf("%d",&n);
     printf("\nEnter the number of resources : ");
     scanf("%d",&m);
     printf("\nEnter allocation matrix : \n");
     
     for (i=0;i<n;i++)
     {
          for (j=0;j<m;j++)
          {
              scanf("%d",&a[i][j]);
          }
     }
     printf("\nEnter MAX matrix : \n");
     for (i=0;i<n;i++)
     {
          for (j=0;j<m;j++)
          {
               scanf("%d",&max[i][j]);
          }
     }
     printf("\nEnter Available Array : \n");
     for (i=0;i<m;i++)
          scanf("%d",&av[i]);
}

void put_data()
{
     printf("\nAllocation matrix is....\n");
     for (i=0;i<n;i++)
     {
          for (j=0;j<m;j++)
          {
               printf("%d\t",a[i][j]);
          }
          printf("\n");
     }
     printf("\nMax Matrix is......\n");
     for (i=0;i<n;i++)
     {
         for (j=0;j<m;j++)
         {
              printf("%d\t",max[i][j]);
         }
         printf("\n");
     }
     printf("\nAvailable Array is.....\n");
     for (i=0;i<m;i++)
         printf("%d\t",av[i]);
}

void calc_need()
{
     for (i=0;i<n;i++)
     {
          for (j=0;j<m;j++)
          {
               need[i][j] = max[i][j]-a[i][j];
          }
     }
     printf("\nNeed Array is.....\n");
     for (i=0;i<n;i++)
     {
          for (j=0;j<m;j++)
          {
               printf("%d\t",need[i][j]);
          }
          printf("\n");
     }
}

void main()
{
     get_data();
     put_data();
     calc_need();
}

Write a program to read book information (bookid, bookname, bookprice, bookqty) in file “book.dat”. Write a menu driven program to perform the following operations using Random access file: i. Search for a specific book by name. ii. Display all book and total cost

  import java . io .*; import java . util .*; class Book {       String name , id ;       int qty ;       double price , total ;       Book ( String i , String n , String p , String q )      {               name = n ;               id = i ;               qty = Integer . parseInt ( q );               price = Double . parseDouble ( p );               total = qty * price ;      }       public String toString ()      {               System . out . println ( "name\t id\t qty\t price\t total" );               String s = name + "\t" + id + "\t" + qty + "\t" + price + "\t" + total ;           ...

Define a class MyDate (day, month, year) with methods to accept and display a MyDate object. Accept date as dd, mm, yyyy. Throw user defined exception “InvalidDateException” if the date is invalid. Examples of invalid dates : 03 15 2019, 31 6 2000, 29 2 2021

  import java . io .*; import java . util .*; class InvalidDateException extends Exception {       InvalidDateException ()       {               System . out . println ( "Invalid Date" );       } } class MyDate {       int day , mon , yr ;       void accept ( int d , int m , int y )       {             day = d ;             mon = m ;             yr = y ;       }       void display ()       {             System . out . println ( "Date is valid : " + day + "/" + mon + "/" + yr );       } } class Date {       public static void main ( String args []) throws Exception       {             Scanner sc = new Sca...

Write a Java program to design a screen using Awt that will take a user name and password. If the user name and password are not same, raise an Exception with appropriate message. User can have 3 login chances only. Use clear button to clear the TextFields.

  import java . awt .*; import java . awt . event .*; import javax . swing .*; class InvalidPasswordException extends Exception {       InvalidPasswordException ()       {             System . out . println ( "Username and password is not same" );       } } public class Password extends Frame implements ActionListener {       Label uname , upass ;       TextField nametext ;       TextField passtext , msg ;       Button login , Clear ;       Panel p ;       int attempt = 0 ;       char c = '*' ;             public void login ()       {             p = new Panel ();             uname = new Label ( "Username : " , Label . CENTER );             upass = n...
