OOPs is the abbreviation for Object-Oriented Programming. OOPs, involve creating objects that contain both data and methods, whereas procedural programming involves the creation of data- and method-containing procedures and methods. OOPs enables programmers to represent real-world scenarios with objects.
[ Releted Article - OOPs Interview Questions ]
The four fundamental OOPs concepts are
Objects are instances or subsets of classes. It is due to a physical operation, such as individual characteristics, qualities, and behavior. It occupies memory space and has defined member functions within a class.
An object's class defines its shape and can only store information of a specific type. Class attributes, such as member functions, variables, and constants, are explicitly named. During operation, it does not consume any memory. In contrast to classes, objects have no existence outside of their own classes.
In OOPs, keywords known as access specifiers or access modifiers are used to define which methods, classes, etc. are available to a given user. To put it another way, encapsulation can be realized with the help of these access specifiers. Access levels such as "public," "private," and "protected" are the most typical. Yet a few more are unique to the various programming languages.
Any class that functions as a parent to other classes is called a superclass or base class. For instance, class Vehicle is a higher-level category than class Car.
A try/catch block is used to handle any exceptions that may occur. The try block initializes a collection of statements that might produce a runtime error. The exception is "caught" by the catch block in its most basic form.
One of the most important parts of OOPs languages is inheritance. Inheritance is the process by which one class takes on another class's features, behaviors, and properties without having to recreate the code.
C and C++ are both programming languages that share many similarities, but there are some key differences between the two.
C++ |
C | |
Language |
C++ is an object-oriented programming (OOP) language. This means that C++ allows for the use of classes and objects to encapsulate data and functionality |
C is a procedural programming language. C uses functions and data structures. |
Complexity |
C++ is generally considered more complex than C |
C is a simpler language that focuses on the basics of programming |
Libraries |
C++ has a larger set of standard libraries, including libraries for I/O, strings, and containers |
C has a smaller set of standard libraries |
Performance |
C++ are low-level languages |
C are low-level languages |
Compatibility |
C++ is largely backward-compatible |
C does not support many of the features introduced in C++ |

In the C programming language, stdio.h is a header file that provides input and output functions. It stands for "standard input-output header". Programs use stdio.h to perform basic input and output operations such as reading from and writing to files, standard input and output streams, and other devices.
Web clients send HTTP requests to servers, telling them what resource they want and what action they want to take. HTTP responses are sent back to clients from servers. They say if the request was successful or not and include the resource that was asked for. HTTP Requests and responses can also include extra information, like headers, to give more context and details. Overall, HTTP responses and requests are the main way that clients and servers exchange information and talk to each other on the web.
The return 0 statement can be utilized within other functions in order to return a value to the function that originally called it. In this case, the return value can be used for various purposes, such as error checking, status reporting, or passing data between functions.
Encapsulation is the process of putting all your data into a single unit and hiding how it works from the people who use it. When we make the data members private, we can't get to them from outside the class. We have to use getters and setters to get to them.
There is no help for threads built in. If they want to know more, you can tell them that it doesn't work with trash collection.

To do this, make two pointers, and assign each one to the linked list's front. Update each as follows:
while (pointer1) {
pointer1 = pointer1->next;
pointer2 = pointer2->next; if (pointer2) pointer2=pointer2->next;
if (pointer1 == pointer2) {
print ("circular\n");
}
}
A pointer that doesn't point anywhere is called a NULL pointer. Such as int *p=NULL;
Although C is generally classified as a high-level language due to its support for high-level programming language operations and its machine independence. It can also be considered a low-level language due to its support for direct memory access, raw pointers, and bit-oriented operation.
In C++, tokens are the smallest parts that make a lot more sense when they are all put together. Tokens can be things like separators, operators, literals, keywords, identifiers, and punctuation.
A pointer is a variable that stores the address of another variable of the same data type. Pointers can be constructed for any data type, including user-defined data types such as class, structure, etc. It permits variable reference passing using the address.
What are some of the key ways in which C++ and Java differ from one another? Which one do you prefer more, and why do you feel that way?
While C++ was developed for use in system and application development, Java is primarily a printing system interpreter and network computing platform. Java's portability across operating systems facilitates its learning by newcomers. C++ requires a specific operating system in order to run. Both are highly useful in their own contexts, and it would be unfair to compare them.
The array is a basic data structure that lets you store more than one item of the same type in a specific order. Arrays are classified into three types:

These are the two categories of C errors:
The database schema is a collection of formulas (sentences) that define the constraints placed on a database to ensure its integrity.

A DBMS is a software that enables the creation and maintenance of databases. A database management system enables the end-user to design and maintain databases. The database management system (DBMS) is the connection between the application/end user and the databases.
A Relational Database Management System (RDBMS) is a program that allows a programmer to interface with a database to add, modify, or delete data. This is performed by user queries (SQL). For instance, each data element could be a database row.
[ Related Article - HBase Vs RDBMS ]
DBMS has many benefits, which are listed below:
A set of statements that can be retrieved by programs that use an RDBMS is called a "stored procedure". These are saved in the database's data dictionary. It can be used to validate data and keep track of who has access to what.
To build a database schema for a new project, one must evaluate the type and volume of data being stored, as well as the anticipated usage patterns and scalability requirements. It is also necessary to normalize the data to decrease redundancy and guarantee consistency. The data should be retrieved and manipulated using efficient queries, and database management systems such as PostgreSQL, MySQL, and MongoDB can be used to construct and manage the database structure.
Some SQL commands are
In SQL Server, there are different kinds of keys.
Here are the ways that ArrayList and Array are different.
Candidate keys in database management systems are the smallest possible set of attributes that can identify a tuple (row) in a relation (table), while super keys are the largest possible set of attributes that can identify a tuple, but may include attributes that aren't strictly necessary for uniqueness.
The term "Data Manipulation Language" (or "DML") refers to the language used to alter information stored in a database. UPDATE, INSERT, SELECT, and DELETE are all examples of such commands.
DDL, which stands for "Data Definition Language," is used to outline the framework for a database. Terms like "ALTER," "CREATE," and "DROP" are all examples of such commands.
A session is a connection between where the communication comes from and where it goes. When implementing a session, a socket is a physical component (IP address and Port Number) that makes the connection possible.

C, Java, C++, Swift, JavaScript, Go, and PHP are the most used programming languages. (You can also talk about the languages you know very well. If you're ready for all of them, you'll definitely get extra credit here.
Virtual function:-polymorphism requires the virtual modifier to be set on the base class functions. A virtual declaration on a base class function makes the execution of a derived class function conditional on the value of the pointer address.
Pure Virtual Function:-This is a base-class function that must be defined in a derived class. In contrast, a pure virtual function is defined as
virtual void fun()=0;
This function will have no effect, and in such a circumstance, the derived function must either implement a pure virtual function itself as a pure virtual function.
The Java virtual machine is referred to as the “JVM for short." The Java runtime environment is used to implement this word (JRE).
