5. Mastering the Fundamentals of C++

Understanding the core concepts is essential for building a solid foundation in C++.

5.1. Basic Syntax and Structure

  • Include Headers: Use #include to include standard library headers (e.g., <iostream> for input/output).
  • Main Function: The main() function is the entry point of every C++ program.
  • Statements: C++ statements end with a semicolon ;.
  • Comments: Use // for single-line comments and /* ... */ for multi-line comments.
#include <iostream> // Include iostream library

int main() {
    // Print "Hello, World!" to the console
    std::cout << "Hello, World!" << std::endl;
    return 0; // Return 0 to indicate successful execution
}

5.2. Data Types

C++ offers various data types to store different kinds of values.

  • int: Integer numbers (e.g., -10, 0, 42).
  • float: Single-precision floating-point numbers (e.g., 3.14, -2.71).
  • double: Double-precision floating-point numbers (e.g., 3.14159265359).
  • char: Characters (e.g., 'A', 'z', '9').
  • bool: Boolean values (true or false).
  • std::string: Strings of characters (e.g., "Hello, C++!").
int age = 30;
float pi = 3.14f;
double precisePi = 3.14159265359;
char initial = 'J';
bool isAdult = true;
std::string name = "John Doe";

5.3. Variables and Constants

Variables store values that can change during program execution, while constants store values that remain constant.

  • Variables: Declared using data_type variable_name;.
  • Constants: Declared using const data_type constant_name = value;.
int x = 10; // Variable
const int y = 20; // Constant
x = 30; // Valid: x can be modified
// y = 40; // Invalid: y cannot be modified

5.4. Operators

Operators perform operations on variables and values.

  • Arithmetic Operators: + (addition), - (subtraction), * (multiplication), / (division), % (modulus).
  • Assignment Operators: = (assignment), += (add and assign), -= (subtract and assign).
  • Comparison Operators: == (equal to), != (not equal to), > (greater than), < (less than), >= (greater than or equal to), <= (less than or equal to).
  • Logical Operators: && (logical AND), || (logical OR), ! (logical NOT).
int a = 10, b = 5;
int sum = a + b; // Addition
int diff = a - b; // Subtraction
bool isEqual = (a == b); // Comparison
bool logicalAnd = (a > 0 && b < 10); // Logical AND

5.5. Control Structures

Control structures manage the flow of execution in a program.

  • if Statements: Executes a block of code if a condition is true.
int age = 20;
if (age >= 18) {
    std::cout << "Adult" << std::endl;
} else {
    std::cout << "Minor" << std::endl;
}
  • switch Statements: Executes different blocks of code based on the value of a variable.
int day = 3;
switch (day) {
    case 1:
        std::cout << "Monday" << std::endl;
        break;
    case 2:
        std::cout << "Tuesday" << std::endl;
        break;
    case 3:
        std::cout << "Wednesday" << std::endl;
        break;
    default:
        std::cout << "Other day" << std::endl;
        break;
}
  • for Loops: Repeats a block of code a specific number of times.
for (int i = 0; i < 5; i++) {
    std::cout << "Iteration: " << i << std::endl;
}
  • while Loops: Repeats a block of code as long as a condition is true.
int count = 0;
while (count < 5) {
    std::cout << "Count: " << count << std::endl;
    count++;
}
  • do-while Loops: Repeats a block of code at least once, as long as a condition is true.
int num = 0;
do {
    std::cout << "Number: " << num << std::endl;
    num++;
} while (num < 5);

5.6. Functions

Functions are reusable blocks of code that perform specific tasks.

  • Function Declaration: Specifies the function’s name, return type, and parameters.
  • Function Definition: Contains the actual code that the function executes.
  • Function Call: Invokes the function to execute its code.
// Function declaration
int add(int a, int b);

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

int main() {
    int result = add(5, 3); // Function call
    std::cout << "Result: " << result << std::endl;
    return 0;
}

5.7. Arrays

Arrays are collections of elements of the same data type.

  • Declaration: data_type array_name[array_size];.
  • Initialization: data_type array_name[array_size] = {value1, value2, ...};.
  • Accessing Elements: Use the index to access array elements (e.g., array_name[0]).
int numbers[5] = {1, 2, 3, 4, 5};
std::cout << "First element: " << numbers[0] << std::endl;

5.8. Pointers

Pointers are variables that store memory addresses.

  • Declaration: data_type *pointer_name;.
  • Address-of Operator: & (returns the address of a variable).
  • Dereference Operator: * (accesses the value stored at the address).
int x = 10;
int *ptr = &x; // Pointer to x
std::cout << "Address of x: " << ptr << std::endl;
std::cout << "Value of x: " << *ptr << std::endl; // Dereferencing

5.9. Strings

Strings are sequences of characters.

  • std::string: Part of the standard library, providing dynamic string manipulation.
#include <string>
#include <iostream>

int main() {
    std::string message = "Hello, C++!";
    std::cout << message << std::endl;
    std::cout << "Length: " << message.length() << std::endl;
    return 0;
}

6. Object-Oriented Programming (OOP) in C++

OOP is a programming paradigm that organizes code around objects, which combine data and behavior.

6.1. Classes and Objects

  • Class: A blueprint for creating objects, defining their attributes (data members) and behaviors (member functions).
  • Object: An instance of a class, representing a specific entity with its own state and behavior.
#include <iostream>
#include <string>

class Dog {
public:
    // Attributes
    std::string name;
    int age;

    // Constructor
    Dog(std::string name, int age) : name(name), age(age) {}

    // Method
    void bark() {
        std::cout << "Woof!" << std::endl;
    }
};

int main() {
    // Create an object of the Dog class
    Dog myDog("Buddy", 3);

    // Access attributes
    std::cout << "Name: " << myDog.name << std::endl;
    std::cout << "Age: " << myDog.age << std::endl;

    // Call method
    myDog.bark();

    return 0;
}

6.2. Encapsulation

Encapsulation is the bundling of data and methods that operate on that data within a class, hiding the internal details from the outside world.

  • Access Specifiers: public, private, and protected control the visibility of class members.
  • Data Hiding: Protecting internal data from direct access, ensuring data integrity.
class BankAccount {
private:
    double balance; // Private attribute

public:
    // Public method to deposit money
    void deposit(double amount) {
        balance += amount;
    }

    // Public method to get balance
    double getBalance() const {
        return balance;
    }
};

int main() {
    BankAccount account;
    account.deposit(1000.0);
    std::cout << "Balance: " << account.getBalance() << std::endl;
    return 0;
}

6.3. Inheritance

Inheritance allows a class (derived class) to inherit attributes and methods from another class (base class), promoting code reuse and hierarchical relationships.

  • Base Class: The class being inherited from.
  • Derived Class: The class that inherits from the base class.
class Animal {
public:
    void eat() {
        std::cout << "Animal is eating" << std::endl;
    }
};

class Dog : public Animal {
public:
    void bark() {
        std::cout << "Dog is barking" << std::endl;
    }
};

int main() {
    Dog myDog;
    myDog.eat(); // Inherited from Animal
    myDog.bark(); // Specific to Dog
    return 0;
}

6.4. Polymorphism

Polymorphism allows objects of different classes to be treated as objects of a common type, enabling flexibility and extensibility.

  • Virtual Functions: Functions declared with the virtual keyword in the base class, allowing derived classes to override their behavior.
  • Abstract Classes: Classes that cannot be instantiated, used as base classes to define a common interface.
class Shape {
public:
    virtual double area() const {
        return 0.0;
    }
};

class Circle : public Shape {
private:
    double radius;

public:
    Circle(double radius) : radius(radius) {}

    double area() const override {
        return 3.14159 * radius * radius;
    }
};

int main() {
    Shape *shape1 = new Shape();
    Shape *shape2 = new Circle(5.0);

    std::cout << "Area of shape1: " << shape1->area() << std::endl;
    std::cout << "Area of shape2: " << shape2->area() << std::endl;

    delete shape1;
    delete shape2;

    return 0;
}

7. Advanced C++ Concepts

Exploring advanced topics will enhance your expertise and allow you to tackle complex programming challenges.

7.1. Templates

Templates enable writing generic code that can work with different data types without being rewritten for each type.

  • Function Templates: Generic functions that operate on different data types.
  • Class Templates: Generic classes that can store and manipulate different data types.
template <typename T>
T max(T a, T b) {
    return (a > b) ? a : b;
}

int main() {
    int x = 5, y = 10;
    double a = 3.14, b = 2.71;

    std::cout << "Max of integers: " << max(x, y) << std::endl;
    std::cout << "Max of doubles: " << max(a, b) << std::endl;

    return 0;
}

7.2. Standard Template Library (STL)

The STL provides a set of template classes for common data structures and algorithms, enhancing productivity and code efficiency.

  • Containers: Data structures like vector, list, map, and set.
  • Algorithms: Functions for sorting, searching, and manipulating data in containers.
  • Iterators: Objects that allow traversal of containers.
#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    std::vector<int> numbers = {5, 2, 8, 1, 9};

    // Sort the vector
    std::sort(numbers.begin(), numbers.end());

    // Print the sorted vector
    for (int num : numbers) {
        std::cout << num << " ";
    }
    std::cout << std::endl;

    return 0;
}

7.3. Memory Management

C++ allows manual memory management using new and delete operators.

  • Dynamic Allocation: Allocating memory at runtime using new.
  • Deallocation: Releasing allocated memory using delete to prevent memory leaks.
  • Smart Pointers: Classes that automatically manage dynamically allocated memory, preventing memory leaks and dangling pointers.
int main() {
    // Dynamic allocation
    int *ptr = new int;
    *ptr = 42;

    std::cout << "Value: " << *ptr << std::endl;

    // Deallocation
    delete ptr;
    ptr = nullptr; // Prevent dangling pointer

    return 0;
}

7.4. Multi-Threading and Concurrency

Multi-threading allows multiple threads to execute concurrently within a single program, improving performance on multi-core processors.

  • Threads: Independent paths of execution within a program.
  • Mutexes: Synchronization primitives that prevent race conditions and ensure thread safety.
  • Condition Variables: Synchronization primitives that allow threads to wait for specific conditions to be met.
#include <iostream>
#include <thread>
#include <mutex>

std::mutex mtx;

void printMessage(const std::string& message) {
    std::lock_guard<std::mutex> lock(mtx);
    std::cout << message << std::endl;
}

int main() {
    std::thread t1(printMessage, "Hello from thread 1");
    std::thread t2(printMessage, "Hello from thread 2");

    t1.join();
    t2.join();

    return 0;
}

7.5. Exception Handling

Exception handling provides a mechanism to handle runtime errors and prevent program crashes.

  • try-catch Blocks: Enclose code that may throw exceptions in a try block and handle exceptions in a catch block.
  • Throwing Exceptions: Use the throw keyword to signal an error condition.
#include <iostream>
#include <stdexcept>

int divide(int a, int b) {
    if (b == 0) {
        throw std::runtime_error("Division by zero!");
    }
    return a / b;
}

int main() {
    try {
        int result = divide(10, 0);
        std::cout << "Result: " << result << std::endl;
    } catch (const std::runtime_error& error) {
        std::cerr << "Exception caught: " << error.what() << std::endl;
    }

    return 0;
}

7.6. Lambda Expressions

Lambda expressions are anonymous functions that can be defined inline, making code more concise and flexible.

#include <iostream>
#include <vector>
#include <algorithm>

int main() {
    std::vector<int> numbers = {1, 2, 3, 4, 5};

    // Use a lambda expression to print even numbers
    std::for_each(numbers.begin(), numbers.end(), [](int num) {
        if (num % 2 == 0) {
            std::cout << num << " ";
        }
    });
    std::cout << std::endl;

    return 0;
}
