Origin of C++ Programming Language

History and Development

The C++ programming language was created by Bjarne Stroustrup at Bell Laboratories in 1979. It was developed as an extension of the C++ programming language with object-oriented features and was originally called "C++ with Classes".

  • Founder : Bjarne Stroustrup (December 30, 1950)
  • Year : 1979-1983
  • Place : Bell Laboratories, USA
  • Purpose : To add object-oriented features to C++ language

    • Bjarne Stroustrup - Father of C++
Advantages of C++
  • Object-oriented programming support
  • Fast and efficient execution
  • Portable across different platforms
  • Rich set of built-in operators
  • Extensive library support (STL)
  • Multiple inheritance support
  • Template programming
Disadvantages of C++
  • Complex syntax
  • No garbage collection
  • Pointer complexity
  • Manual memory management
  • Less secure compared to modern languages
C++ Programming Learning Roadmap
  1. Basics
    • Syntax and Structure
    • Variables and Data Types
    • Operators and Expressions
    • Input/Output Streams
  2. Control Flow
    • Conditional Statements (if, switch)
    • Loops (for, while, do-while)
    • Break and Continue
  3. Object-Oriented Programming
    • Classes and Objects
    • Inheritance and Polymorphism
    • Encapsulation and Abstraction
  4. Advanced Features
    • Templates
    • Exception Handling
    • STL Containers
  5. Advanced Concepts
    • Smart Pointers
    • dynamic Memory Management
    • Operator Overloading
    • File Handling
Key Concepts in C++
  • Object-Oriented Programming : Classes, inheritance, polymorphism
  • Templates : Generic programming and STL
  • Exception Handling : try, catch, throw
  • Memory Management : new, delete operators
  • Standard Template Library : Containers, algorithms, iterators
  • Namespaces : Organizing code and avoiding naming conflicts
First C++ Program - Hello World

The "Hello, World!" program is a simple C++ program that displays the message "Hello, World!" on the screen. It's often used as a starting point for learning a new programming language. Here's the code:

   #include <iostream>
   using namespace std;

   int main() {
   cout << "Hello, World!" << endl;
   return 0;
   }
