 Create a class product, take appropriate data members and functions which calculate net profit for a product after selling the product.

Create a class switchboard. Create a function that returns how many possible outcomes can come from a certain number of switches (on / off). In other words, for a given number of switches, how many different combinations of on and off can we have?

Given two dates D1 and D2, write a program to count the number of Saturdays and Sundays from D1 to D2 (including D1 and D2).

The date in string format is like "8 Feb 2021".Input

The first line of input will contain date D1 in the string format.

The second line of input will contain date D2 in the string format.Output

The output should be a single line containing two integers separated by space.Explanation

For example, if the given dates are "25 Jan 2021" and "14 Feb 2021", the Saturdays and Sundays dates from "25 Jan 2021" to "14 Feb 2021" are

"30 Jan 2021" is a Saturday

"31 Jan 2021" is a Sunday

"6 Feb 2021" is a Saturday

"7 Feb 2021" is a Sunday

"13 Feb 2021" is a Saturday

"14 Feb 2021" is a Sunday

So the output should be

Saturday: 3

Sunday: 3

Sample Input 1

25 Jan 2021

14 Feb 2021

Sample Output 1

Saturday: 3

Sunday: 3

Q1.Define class Student with the following attributes and member functions.

i. Date of Birth (constant data member) ii. Pointer to char for name iii. Pointer to char for Department iv. Student ID (constant data member) v. Member function Constructors vi. Member function Destructor vii. Member function to modify state of the object viii. Member function to display state of the object (should be constant) Note that pointers in (ii) and (iii) should point to the dynamic memory allocated for name and Department name. Get information of the student object in constructor. Memory for name and Department will be allocated in constructor using dynamic memory allocation. Destructor will release memory to the operating system.

Q.3. Extend Q.2 for shallow and deep copy constructor

write a method called secondLargest that takes an array of integers and returns the second largest element in the array

write a method called insert that inserts an element into an integer array. It should take 3 parameters: an int array, the number to be inserted and the index it should be inserted at. It should return a new array that has the element inserted at the index (the new array should have a length 1 longer than the original array).

write two method called findIndex and findLastIndex that search for a number in an array. they should take an int array and an int as parameters. findIndex should return the index of the first instance of the number in the array. findLastIndex should return the index of the last instance of the number in the array. They both should return -1 if the number is not found. Do not use any library methods

Use method overriding to write two methods called printArray. On should take an int array and the other should take a double array. Both should print the array they are given as an argument
