A prime number program checks if a given number is divisible only by 1 and itself.

• A prime number is a positive integer greater than 1 that has no positive integer divisors other than 1 and itself.

• To check if a number is prime, we can divide it by all numbers from 2 to the square root of the number.

• If the number is divisible by any of these numbers, it is not prime.

• If the number is not divisible by any of these numbers, it is prime.

Overloading is when a single function or method has multiple definitions with different parameters. Overriding is when a subclass provides a specific implementation for a method that is already defined in its superclass.

• Overloading occurs within the same class, while overriding occurs between a superclass and its subclass

• Overloading is resolved at compile time based on the number and type of arguments, while overriding is resolved at runtime based on the object type

• Example of...read more

Market-basket analysis is a technique used in data mining to discover relationships between items purchased together.

• It involves analyzing customer purchase data to identify patterns and associations between products frequently bought together.

• The results can be used for strategies like product placement, cross-selling, and targeted marketing.

• Example: If customers who buy bread also tend to buy butter, a store may place these items close to each other to increase sales.

Business processes and configurations are essential for efficient operations.

• Business processes refer to the set of activities and tasks that are performed to achieve a specific goal or objective.

• Both business processes and configurations are important for ensuring efficient operations and maximizing productivity.

• For example, a company may have a b...read more

Overloading is when a method has the same name but different parameters in the same class, while overriding is when a method in a subclass has the same name and parameters as a method in its superclass.

• Overloading occurs within the same class, while overriding occurs in a subclass.

• Overloading involves methods with the same name but different parameters, while overriding involves methods with the same name and parameters.

• Overloading is resolved at compile time, while overridin...read more

Python is a high-level, interpreted programming language known for its simplicity and readability.

• Python is used for web development, data analysis, artificial intelligence, and more.

A queue is a data structure that follows the First-In-First-Out (FIFO) principle.

• Elements are added to the back of the queue and removed from the front.

• Common operations include enqueue (add to back) and dequeue (remove from front).

• Examples include waiting in line, printing jobs, and processing tasks in order.

I believe AI has the potential to revolutionize industries and improve efficiency, but also raises ethical concerns.

• AI can automate repetitive tasks and improve productivity

• AI can analyze large amounts of data quickly and accurately

• AI can assist in medical diagnosis and treatment planning

• Ethical concerns include job displacement and bias in algorithms

Oops concepts are fundamental to object-oriented programming. Real-time examples include inheritance, polymorphism, and encapsulation.

• Inheritance: A car is a vehicle, but a vehicle is not necessarily a car.

• Polymorphism: A shape can be a square, rectangle, or triangle, but they all have a common method of calculating area.

• Encapsulation: A bank account has private data such as balance and account number, which can only be accessed through specific methods.

Java and C are both programming languages used for developing software applications.

• Java is an object-oriented language while C is a procedural language.
