Introduction to C++

What is C++ ?

C++ is a cross-platform, object-oriented programming language that is powerful, flexible, and widely used for systems and application development.

    Features of C++ Programming :

  • C++ is a middle-level language (supports both low-level and high-level programming).
  • It is case sensitive.
  • It is extensible and supports object-oriented concepts (classes, inheritance, polymorphism, encapsulation, abstraction).
  • Highly portable across platforms and compilers.
  • It offers high performance — suitable for performance-critical applications.
  • Widely used in operating systems, embedded systems, game engines, and high-performance applications.
  • It provides both low-level memory control (pointers) and high-level abstractions (STL, classes).
Uses of C++

C++ is used for:

  • System and operating system development (kernels, drivers).
  • Game development and real-time simulation engines.
  • Embedded systems and firmware.
  • High-performance applications (finance, scientific computing).
  • Desktop applications and GUI tools.
  • Compilers, interpreters and development tools.
  • Libraries (STL, Boost) and reusable components.
Father of C++ Programming ?

Bjarne Stroustrup is generally considered the father of C++.

He began developing C++ (initially called "C with Classes") in 1979, and the language was first published and made widely available in the mid-1980s (notably with the 1985 book The C++ Programming Language).

Stroustrup designed the language's major facilities and produced the first implementations; he also contributed to the language's standardization process.

Early distributions and textbooks helped C++ gain adoption through the 1980s and 1990s.

Features of C++ Programming :

Small / Simple Concepts

  • C++ provides a core set of keywords and constructs that allow concise expression of algorithms and data structures.
  • Fundamental concepts (variables, control flow, functions) are straightforward to learn, while advanced features enable powerful abstractions.

Speed

  • C++ delivers high execution speed and low overhead, which is why it is used for performance-critical software.
  • It is often chosen where close-to-hardware control and efficiency are required.

Modularity

  • C++ supports modular programming via functions, classes, and namespaces which make large projects easier to organize and maintain.

Case Sensitive

  • C++ is case sensitive — identifiers like Var and var are different.

Middle-level Language

  • C++ combines low-level memory manipulation with high-level abstractions, making it suitable for both system and application programming.

Structured and Object-Oriented

  • C++ supports structured programming and full object-oriented features (classes, inheritance, polymorphism, encapsulation).

Memory Management

  • C++ provides manual and dynamic memory management (new/delete, smart pointers) giving fine-grained control over resources.

Rich Standard Library

  • The C++ Standard Library (including the STL) offers containers, algorithms, iterators and utilities that speed development.

Pointers and Recursion

  • C++ supports pointers for direct memory access and recursion for elegant algorithm design where applicable.

Extensible

  • C++ is extensible — you can create user-defined types, templates, and libraries to add new functionality.

Fast

  • Because of its low-level capabilities and compiled nature, C++ programs can be extremely fast when optimized properly.
