Data storage classes in C++
C++ provides several data storage classes, including 'auto', 'register', 'static', 'extern', and 'mutable'.
The 'auto' storage class is the default and is used for local variables.
The 'register' storage class is used to define local variables that should be stored in CPU registers for faster access.
The 'static' storage class is used for variables that retain their values across function calls.

OOP's concepts include encapsulation, inheritance, and polymorphism.
Encapsulation: Bundling data and methods together in a class.
Inheritance: Creating new classes from existing ones, inheriting their properties and behaviors.
Polymorphism: Objects of different classes can be treated as objects of a common superclass.
Example: A class 'Car' encapsulates data like 'color' and methods like 'startEngine'.
Example: Class 'SUV'...
Static polymorphism is resolved at compile-time, while runtime polymorphism is resolved at runtime.
Static polymorphism is achieved through function overloading and operator overloading.
Runtime polymorphism is achieved through virtual functions and function overriding.
Static polymorphism is faster as it is resolved at compile-time, while runtime polymorphism incurs overhead at runtime.
Static polymorphism is also known a...
Smart pointers are objects that manage the lifetime of dynamically allocated memory in C++.
Smart pointers automatically deallocate memory when it is no longer needed.
They prevent memory leaks and dangling pointers.
Examples of smart pointers in C++ are unique_ptr, shared_ptr, and weak_ptr.
New and delete operators are used for dynamic memory allocation in C++.
New operator is used to allocate memory dynamically for an object or an array.
Delete operator is used to deallocate the memory allocated by new operator.
New operator returns a pointer to the allocated memory.
Delete operator takes a pointer to the memory to be deallocated.
If delete is called on a null pointer, no action is taken.
Programs related to class and OOP
Create a class with attributes and methods
Implement inheritance and polymorphism
Use encapsulation to hide data
Demonstrate the concept of abstraction
Create objects and call their methods

Aggregation functions are used to perform calculations on groups of data in a database.
Aggregation functions include COUNT, SUM, AVG, MAX, and MIN.
They are used with the GROUP BY clause to group data based on a specific column.
COUNT function returns the number of rows in a table or the number of non-null values in a column.
SUM function returns the sum of values in a column.
AVG function returns the average of values in ...
Two ways to write a sentence in mirror image form in Java: reverse string function and array conversion.
Use the reverse() method of the String class to reverse the sentence
Convert the sentence to a character array, then swap the first and last characters, second and second-to-last characters, and so on until the middle is reached
Example: 'Hello World' becomes 'dlroW olleH'
Static is used in public static void main to allow the method to be called without creating an instance of the class.
Static methods belong to the class and not to any instance of the class.
The main method is the entry point of a Java program and needs to be called without creating an object of the class.
The static keyword allows the main method to be called directly from the class, without creating an instance of the c...
Abstract classes, interfaces, and enums provide abstraction and modularity in Java.
Abstract classes provide a partial implementation of a class and cannot be instantiated.
Interfaces define a set of methods that a class must implement and can be used for multiple inheritance.
Enums provide a set of named constants.
All three are used for abstraction and modularity in Java.
Abstract classes and interfaces are used for polym...
Object-oriented software engineering is a framework for designing and developing software using objects.
Object-oriented software engineering is a methodology for designing and developing software using objects.
It involves creating classes and objects that encapsulate data and behavior.
Frameworks are pre-built structures that provide a foundation for building software applications.
Frameworks can include libraries, APIs,...
Java is an object-oriented language with features like inheritance, encapsulation, and polymorphism.
Inheritance allows classes to inherit properties and methods from other classes.
Encapsulation hides the implementation details of a class from other classes.
Polymorphism allows objects to take on multiple forms or behaviors.
Java also supports abstraction, interfaces, and exception handling.
Example: class Car extends Vehi...
Normalization is a process of organizing data in a database to reduce redundancy and dependency.
Normalization is used to eliminate data redundancy and improve data integrity.
It involves dividing a database into two or more tables and defining relationships between them.
There are different levels of normalization, such as first normal form (1NF), second normal form (2NF), and so on.
Normalization helps in efficient data ...
ADBMS stands for Advanced Database Management System which is an extension of DBMS with additional features.
ADBMS has advanced features like data mining, data warehousing, and online analytical processing.
ADBMS is used for handling large and complex data sets.
DBMS is a basic system for managing data and is used for small and simple data sets.
DBMS does not have advanced features like ADBMS.
Examples of ADBMS are Oracle, ...
