Practical-1: Develop a Kotlin program for demonstrating various programming concepts.

1.1. Store & Display Values in Different Variables: Create and display variables of different data types, including Integer, Double, Float, Long, Short, Byte, Char, Boolean, and String

1.2. Type Conversion: Perform type conversions such as Integer to Double, String to Integer, and String to Double.

1.3. Scan student’s information and display all the data: Input and display data of students, including their name, enrolment no, branch,etc.

1.4. Check Odd or Even Numbers: Determine whether a number is odd or even using control flow within println() method.

1.5. Display Month Name: Use a when expression to display the month name based on user input.

1.6. User-Defined Function: Create a user-defined function to perform arithmetic operations (addition, subtraction, multiplication, division) on two numbers

1.7. Factorial Calculation with Recursion: Calculate the factorial of a number using recursion.

1.8. Working with Arrays: Explore array operations such as Arrays.deepToString(), contentDeepToString(), IntArray.joinToString(), and use them to print arrays. Utilize various loop types like range, downTo, until, etc., to manipulate arrays. Sort an array of integers both without using built-in functions and with built-in functions.

1.9. Find Maximum Number from ArrayList: Write a program to find the maximum number from an ArrayList of integers.

1.10. Class and Constructor Creation: Define different classes and constructors. Create a "Car" class with properties like type, model, price, owner, and miles driven. Implement functions to get car information, original car price, current car price, and display car information

1.11. Operator Overloading and Matrix Operations: Explain operator overloading and implement matrix addition, subtraction, and multiplication using a "Matrix" class. Overload the toString() function in the "Matrix" class for customized output.

1. Swap Value of two variables without using third variable and with using third variable.

2. Create two class named as Product and Laptop. Inherit with this information: Product class should be parent and child class should be Laptop class. 

Add Product Name, Quantity, Amount per Quantity in Product class. In Laptop class add CPU name, RAM size, HDD Size, etc. of Laptop configuration. 

Create primary and secondary Constructor of both class. 

If Primary constructor is there then can we create secondary constructor in inheritance? 

If we can create secondary and primary constructor both in child class then what is restriction if parent have more than two different secondary constructor? 

Create List of 5 laptops in ArrayList and display all objects information.

3. Create two class named as Person and Student. Inherit with this information: Person class should be parent and child class should be Student class. 

Add first name, last name, age in Person class. In Laptop class add enrollment no, branch, class, lab batch, etc. 

Create primary and secondary Constructor of both class. 

Create List of 5 students in ArrayList and display all objects information.
