A view in SQL is a virtual table that is based on the result of a query. It can be used to simplify complex queries and provide a logical representation of data.
A view is created by using the CREATE VIEW statement in SQL.
It is defined by a query that retrieves data from one or more tables.
Views can be used to hide complexity and provide a simplified interface to the underlying data.
They can also be used to restrict acc...
The kernel is the core component of an operating system that manages system resources and provides a bridge between hardware and software.
The kernel is loaded into memory during the boot process.
It manages memory, processes, and device drivers.
It provides system calls for applications to interact with hardware.
Examples of kernels include Linux kernel, Windows NT kernel, and macOS kernel.

In Python, we can use the 'import' statement to import a variable from another file.
We can also use the 'export' statement in the source file to export the variable and then import it in the destination file.
The syntax ...

Constructors are special methods in a class that are used to initialize objects of that class.
Constructors have the same name as the class they belong to.
They are called automatically when an object is created.
Constructors can have parameters to initialize object properties.
Example: public class Car { public Car(String color) { this.color = color; }}
Design patterns in C++ are reusable solutions to common problems in software design.
Design patterns help in creating flexible, maintainable, and scalable code.
Examples of design patterns in C++ include Singleton, Factory, Observer, and Strategy.
Each design pattern has its own purpose and can be applied in different scenarios.
Understanding design patterns can improve code quality and efficiency.

Structure is a collection of variables of different data types while union is a collection of variables of same data type.
Structure allocates memory for all its variables while union allocates memory for only one variable at a time.
Structure is used when we want to store different types of data while union is used when we want to store only one type of data.
Structure is accessed using dot operator while union is access...
Dangling pointers can be avoided by setting them to NULL after freeing the memory they point to.
Always initialize pointers to NULL.
Set pointers to NULL after freeing the memory they point to.
Avoid accessing memory through a pointer after it has been freed.
Use smart pointers or garbage collection to automate memory management.
A program to print Fibonacci series using recursion.
Define a recursive function that takes an integer n as input
Base case: if n is 0 or 1, return n
Recursive case: return the sum of the previous two Fibonacci numbers
