## Introduction
- Briefly introduce C++ and its history.
- Explain why C++ is a popular programming language.

## Setting up the Environment
- Guide on installing a C++ compiler (e.g., g++) and a code editor (e.g., Visual Studio Code).
- Explain how to write and compile a simple C++ program.

```cpp
#include <iostream>
using namespace std;

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

## Basics of C++
### Variables and Data Types
- Discuss different data types (int, float, double, char, etc.).
- Explain how to declare and initialize variables.
- Show examples of type conversions.

```cpp
int age = 30;
float salary = 50000.50;
char grade = 'A';
```

### Operators
- Cover arithmetic, relational, logical, and assignment operators.
- Provide examples of their usage.

```cpp
int a = 5, b = 3;
int sum = a + b;
bool isGreater = (a > b);
```

### Control Structures
- Explain if statements, switch statements, and loops (for, while, do-while).
- Provide examples for each.

```cpp
if (age >= 18) {
    cout << "You are an adult." << endl;
}

for (int i = 0; i < 5; i++) {
    cout << i << endl;
}
```

### Functions
- Describe how to declare and define functions.
- Explain function parameters and return values.

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

### Arrays and Vectors
- Introduce arrays and vectors.
- Show how to declare, initialize, and access elements.

```cpp
int numbers[5] = {1, 2, 3, 4, 5};
vector<string> names = {"Alice", "Bob", "Charlie"};
```

## Object-Oriented Programming (OOP)
### Classes and Objects
- Explain the concept of classes and objects.
- Provide an example of a class definition and object creation.

```cpp
class Person {
public:
    string name;
    int age;
};

Person person1;
person1.name = "Alice";
person1.age = 25;
```

### Inheritance
- Describe inheritance and derived classes.
- Show how to create derived classes and override base class methods.

```cpp
class Animal {
public:
    void speak() {
        cout << "Animal speaks" << endl;
    }
};

class Dog : public Animal {
public:
    void speak() {
        cout << "Dog barks" << endl;
    }
};
```

### Polymorphism
- Explain polymorphism and virtual functions.
- Provide an example of using polymorphism.

```cpp
class Shape {
public:
    virtual void draw() {
        cout << "Drawing a shape" << endl;
    }
};

class Circle : public Shape {
public:
    void draw() override {
        cout << "Drawing a circle" << endl;
    }
};
```

## Standard Library
- Introduce key components of the C++ Standard Library (e.g., vectors, strings, algorithms).
- Provide examples of common library functions.

```cpp
#include <vector>
#include <string>
#include <algorithm>

vector<int> numbers = {5, 2, 8, 1, 3};
sort(numbers.begin(), numbers.end());
```

## File Handling
- Explain how to read from and write to files.
- Provide examples of file I/O operations.

```cpp
#include <fstream>
using namespace std;

ofstream outfile("example.txt");
outfile << "Hello, File!";
outfile.close();
```

## Exception Handling
- Describe exception handling using try-catch blocks.
- Show how to handle exceptions.

```cpp
try {
    int result = divide(10, 0);
} catch (const runtime_error &e) {
    cout << "Error: " << e.what() << endl;
}
```
