C++ Introduction

10 March 17, 2023

Hi everyone, inside this article we will see about C++ Introduction, Characteristics, Application Use, etc.

What is C++?

C++ is a high-level, general-purpose programming language designed for system and application programming. It was developed as an extension of the C language and has influenced many other programming languages. It is widely used for developing operating systems, games, and other system software.

Use of C++

C++ is used for developing a wide range of applications, including:

  • System software: Operating systems, device drivers, embedded systems, etc.
  • Game development
  • Financial applications
  • Scientific simulations and research
  • Databases and big data processing
  • Web development and server-side programming
  • GUI based applications, such as desktop applications
  • Machine learning and artificial intelligence.

Characteristics of C++

C++ has the following characteristics:

  • Object-Oriented: Supports object-oriented programming, which allows for the creation of objects and classes.
  • High-level: Abstraction from low-level hardware details, making it easier to write and maintain code.
  • Fast: C++ is faster than other high-level programming languages, making it suitable for developing performance-critical applications.
  • Statically typed: Variables must be declared with a specific data type, which is checked at compile time.
  • Compiled: Source code is transformed into machine code before execution, resulting in faster execution times.
  • Portable: Programs written in C++ can be run on different platforms with minimal modifications.
  • Standardized: Has an internationally recognized standard, known as the ISO Standard.

About Few C++ Standard Libraries

C++ has a large standard library that provides a wide range of facilities, including:

  • iostream: Input/output operations, such as reading and writing to the console.
  • string: String manipulation and concatenation.
  • algorithm: A collection of algorithms for sorting, searching, and performing other common operations.
  • vector: Dynamic arrays for storing collections of objects.
  • map: Associative arrays for storing key-value pairs.
  • utility: A collection of generic utility functions.

These libraries provide a high-level interface to common programming tasks, allowing developers to write efficient and maintainable code.

Object-Oriented Programming (OOPs) Features of C++

C++ supports object-oriented programming (OOP) and has the following OOP features:

  • Classes: A blueprint for creating objects, defining data members (attributes) and member functions (methods) that operate on the data.
  • Objects: Instances of a class, representing real-world entities.
  • Inheritance: A mechanism for creating a new class based on an existing class, with the ability to add or override features.
  • Polymorphism: The ability of objects to take on different forms, allowing objects of different classes to be treated as objects of a common class.
  • Encapsulation: The bundling of data and functions within an object, hiding implementation details and allowing objects to be treated as black boxes.
  • Abstraction: The process of hiding implementation details and exposing only the essential features of an object to the outside world.

A Basic Program

#include <iostream>
using namespace std;

int main() {
  cout << "Hello Skillshike Team!";
  cout << "\n";
  cout << "I am learning C++";
  return 0;
}

Output

Hello Skillshike Team!
I am learning C++
