)Create a class named 'Member' having the following members: Data members 1 - Name 2 - Age 3 - Phone number 4 - Address 5 - Salary It also has a method named 'printSalary' which prints the salary of the members. Two classes 'Employee' and 'Manager' inherits the 'Member' class. The 'Employee' and 'Manager' classes have data members 'specialization' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a manager by making an object of both of these classes and print the same.

Write a program to count the number of prime number elements in an array of 10 elements where array is allocated memory dynamically

Write the PHP script called remove.php and create an HTML form for your web page that removes lines of text from a given file, the file contains sentences, and it is called textfile.txt. Your we page contains a short form with a text box and text field where the customers or users can type only one word. Then the web page should provide the following behaviors: • The web page displays the current contents of the file text.txt as it appears in the file with its format.• The web page form submits back to the same page, remove.php, as a post request. • Display changes of the file to any future viewings of the web page and display how many sentences were removed from the textfile.txt. • Do not used browser's default styling. You are required to write any suitable CSS style. • Ensure that the results are displayed in red color and the number of sentences removed are displayed in green colour.

If the network is to be divided into four subnetworks having 50 machines each give a plan to do so. What additional devices will be needed? Give the IP address of each subnetwork and the address ranges for hosts in each subnetwork.

Q.1

(a) Generate data with the function y = ax³+ bx²+ cx + d in the range of x as it

varies from 0 to 2 with step increase of h . Assign suitable values of constants a, b, c and d.

Also assume the increment h to any value in between 0.1 to 0.25.

(b) Using the data obtained in (a), determine [dy/dx]_x=p and [d²y/dx²]_x=q

. Assign suitable values of p and q in the range 0.1 to 0.6.

(c) Compare your result with the original one and make a conclusion.
