🌐 Introduction to C++ Programming

C++ is a powerful, high-performance programming language that extends the C language by adding object-oriented programming (OOP) features, along with many modern programming capabilities. It is widely used in system software, game development, embedded systems, and high-performance applications.

In simple terms:

C++ = C + Object-Oriented + High Performance

C++ supports multiple programming paradigms:

Procedural
Object-Oriented
Generic (templates)

🧠 Importance of C++

Combines low-level and high-level programming
Used in performance-critical applications
Foundation for many modern technologies
Widely used in competitive programming
Supports OOP and reusable code

🧩 Basic Structure of a C++ Program

📄 Example Program

#include <iostream>
using namespace std;

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

🧠 Components:

#include → Header files
namespace → Scope management
main() → Entry point
cout → Output

⚙️ Data Types in C++

🔢 Basic Data Types

Type	Description
int	Integer
float	Decimal
double	High precision
char	Character
bool	Boolean

🧩 Derived Types

Arrays
Pointers
References

🧠 User-Defined Types

struct
class
enum

🔤 Variables and Constants

📌 Variables

int x = 10;

🔒 Constants

const int MAX = 100;

⚙️ Operators in C++

🔢 Types:

Arithmetic (+, -, *, /)
Relational (==, >, <)
Logical (&&, ||)
Bitwise (&, |, ^)
Assignment (=, +=)

🧮 Bitwise Operations

🔄 Control Structures

🔀 Decision Making

🔁 Loops

🧠 Functions in C++

📌 Definition

int add(int a, int b) {
    return a + b;
}

⚙️ Features:

Function overloading
Inline functions
Recursion

🧩 Object-Oriented Programming (OOP)

🧠 Core Concepts

🔹 1. Class and Object

class Car {
public:
    int speed;
};

🔹 2. Encapsulation

Data hiding
Use of access modifiers

🔹 3. Inheritance

Reuse of code

🔹 4. Polymorphism

Function overloading
Operator overloading

🔹 5. Abstraction

Hide implementation details

🧠 Arrays in C++

Same as C but with enhancements

🔤 Strings in C++

📌 Types:

C-style strings
std::string

🧠 Pointers and References

📌 Pointers

🔄 References

Alias for variables

int &ref = x;

💾 Dynamic Memory Allocation

📦 Operators:

new
delete

🧩 Structures and Classes

⚖️ Difference:

Feature	Struct	Class
Default Access	Public	Private

📂 File Handling

📄 Streams:

ifstream
ofstream
fstream

🧠 Standard Template Library (STL)

📦 Components

Containers (vector, list, map)
Algorithms (sort, search)
Iterators

⚙️ Exception Handling

🔥 Concept:

try {
    // code
} catch (...) {
    // handle error
}

🧠 Templates (Generic Programming)

📌 Example:

template <typename T>
T add(T a, T b) {
    return a + b;
}

🌐 C++ in Software Development Context

🧠 Role Among Languages

🔹 Compared to Other Languages:

Language	Type	Use
C++	OOP + Low-level	Systems, games
Python	High-level	AI, scripting
Java	OOP	Enterprise

🌐 Introduction to C Programming

C programming is one of the most influential and widely used programming languages in the world. Developed in the early 1970s, it is a general-purpose, procedural programming language that provides low-level access to memory and system resources.

In simple terms:

C = powerful language that connects software with hardware

C is often called the mother of modern programming languages because many languages (like C++, Java, Python) are derived from or influenced by it.
