 basic concepts of the C++ programming language:



  1. Introduction to C++

    • C++ is a general-purpose programming language developed by Bjarne Stroustrup.
    • It supports features like object-oriented programming, type checking, and exception handling.
    • It is considered a "better C" with additional features.
    • C++ is used for system/software, game development, drivers, client-server applications, and embedded firmware.

  2. Features of C++

    • Better memory management with new and delete.
    • Supports object-oriented programming concepts: Abstraction, Inheritance, Encapsulation, and Polymorphism.
    • It is portable due to ANSI standard compliance but not fully platform-independent because of system-specific traits like graphics.
    • Structured programming with a focus on functions to improve readability and reusability.
    • Exception handling similar to Java for handling runtime errors.
    • Provides ease of use once the syntax is understood.

  3. Basic Syntax

    • A C++ program typically starts with including headers like iostream for input-output operations.
    • The program execution starts from the main() function.
    • The standard output is handled by cout, and inputs by cin.
    • Use of // for single-line comments and /* */ for multi-line comments.

  4. Variables and Data Types

    • Variables must be declared with a data type, e.g., int, float, double, char.
    • C++ supports different data types for various kinds of data processing.
    • Data type modifiers like unsigned, short, and long modify the behavior of fundamental data types.

  5. Control Statements

    • C++ provides control statements such as if, else, switch for decision making.
    • Loops such as for, while, and do-while help in executing code multiple times.

  6. Functions

    • Functions allow code reusability and better organization.
    • Include default arguments, recursion, and overloading to enhance functionality.

  7. Object-Oriented Programming (OOP)

    • Concepts include classes and objects, inheritance, polymorphism, encapsulation, and abstraction.
    • Access specifiers control the visibility of class members.

  8. Exception Handling

    • Use try, catch, and throw to manage exceptions, ensuring that the program can handle runtime errors gracefully.

  9. Memory Management

    • Use pointers for direct memory access.
    • Use new and delete for dynamic memory allocation.

  10. Compiling and Running C++ Programs

    • Save the code with a .cpp extension.
    • Use a compiler like g++ to compile the code into an executable file, e.g.,
      bash
      g++ program.cpp -o program
./program
