🚀 Why Learn C++?

C++ is a general-purpose programming language created as an extension of the C programming language. It is used in a wide range of applications, including:

  • Game development
  • System and application software
  • Embedded systems
  • Operating systems (like Windows/Linux components)
  • Competitive programming

Learning C++ gives you a deep understanding of how software works at a low level, and it strengthens your logic and algorithmic thinking.

📘 What You'll Learn in This C++ Tutorial Point

This C++ tutorial point is divided into small, digestible lessons that focus on writing and understanding code, not just theory. We believe in "learning by doing" — and that's what makes this one of the best C++ tutorials available online for free.

Here are the core topics we'll cover:

  1. Introduction to C++
  2. Data Types and Variables
  3. Control Structures
  4. Functions in C++
  5. Object-Oriented Programming
  6. Pointers and Memory
  7. STL (Standard Template Library)
  8. Project: Mini Banking System

🔍 1. Introduction to C++

C++ is a compiled, statically typed language. Here’s your first Hello World program in C++:

#include <iostream> using namespace std; int main() { cout << "Hello, World!" << endl; return 0; }
Enter fullscreen mode Exit fullscreen mode

Key Points:

  • #include <iostream> lets you use cout for output.
  • main() is the entry point of the program.
  • endl adds a newline after output.

📊 2. Data Types and Variables

C++ supports various data types including int, float, char, and bool.

int age = 25; float height = 5.9; char grade = 'A'; bool isStudent = true;
Enter fullscreen mode Exit fullscreen mode

These variables store values that can be used throughout your program.

🔁 3. Control Structures

Conditional and looping statements help you control the flow of your program.

Example: if-else and for loop 

int num = 10; if (num > 5) { cout << "Number is greater than 5" << endl; } else { cout << "Number is 5 or less" << endl; } for (int i = 1; i <= 5; i++) { cout << i << " "; }
Enter fullscreen mode Exit fullscreen mode

⚙️ 4. Functions in C++

Functions allow you to organize your code into reusable blocks.

int add(int a, int b) { return a + b; } int main() { cout << "Sum is: " << add(5, 3) << endl; return 0; }
Enter fullscreen mode Exit fullscreen mode

🧱 5. Object-Oriented Programming (OOP)

C++ is famous for supporting OOP principles: classes, objects, inheritance, and polymorphism.

Example: Class and Object 

class Car { public: string brand; void start() { cout << brand << " is starting..." << endl; } }; int main() { Car myCar; myCar.brand = "Toyota"; myCar.start(); }
Enter fullscreen mode Exit fullscreen mode

📌 6. Pointers and Memory

C++ lets you work directly with memory using pointers.

int val = 10; int* ptr = &val; cout << "Value: " << *ptr << endl; cout << "Address: " << ptr << endl;
Enter fullscreen mode Exit fullscreen mode

This is useful in dynamic memory allocation and low-level programming.

📦 7. STL (Standard Template Library)

The STL is a powerful feature in C++ that provides ready-to-use classes and functions.

Example: Using vector 

#include <vector> vector<int> nums = {1, 2, 3}; nums.push_back(4); for (int n : nums) { cout << n << " "; }
Enter fullscreen mode Exit fullscreen mode

🧠 8. Mini Project: Simple Banking System

Here’s a very basic idea of a banking system using classes:

class Bank { string name; int balance; public: Bank(string user, int initial) { name = user; balance = initial; } void deposit(int amount) { balance += amount; } void display() { cout << "User: " << name << ", Balance: ₹" << balance << endl; } }; int main() { Bank user1("Rahul", 5000); user1.deposit(2000); user1.display(); }
Enter fullscreen mode Exit fullscreen mode
