A pointer is a variable that stores the memory address of another variable. It is used to manipulate data indirectly.

• Pointers allow for dynamic memory allocation

• Pointers can be used to pass data between functions efficiently

• Pointers are used extensively in data structures such as linked lists and trees

A program to check if a number is prime or not.

• A prime number is only divisible by 1 and itself.

• Loop through all numbers from 2 to n-1 and check if n is divisible by any of them.

• If n is divisible by any number, it is not prime.

• If n is not divisible by any number, it is prime.

Bubble sort is a simple sorting algorithm that repeatedly steps through the list, compares adjacent elements and swaps them if they are in the wrong order.

• Start from the first element and compare it with the next element

• If the first element is greater than the next element, swap them

• Repeat this process for all elements in the list

• Continue this process until no more swaps are needed

Data abstraction and encapsulation are OOP concepts that help in hiding implementation details and providing a simplified interface.

• Data abstraction is the process of hiding implementation details while showing only the necessary information to the user.

• Encapsulation is the process of wrapping data and code into a single unit, preventing direct access to data from outside the unit.

• Example of data abstraction: A car das...read more

Data structure is a way of organizing and storing data in a computer so that it can be accessed and used efficiently.

• Data structures help in efficient data storage and retrieval

• They provide a way to organize and manage large amounts of data

• Examples include arrays, linked lists, trees, and graphs

A database is a collection of data organized in a structured way. Normalization is the process of organizing data to minimize redundancy.

• A database is used to store and manage data.

• Normalization is the process of breaking down data into smaller, more manageable pieces.

• Normalization helps to minimize data redundancy and improve data consistency.

• There are different levels of normalization, such as first normal form (1NF)...read more
