C++ Programming for Beginners

C++ is a powerhouse language for performance-critical systems, games, and applications. This guide will walk you through its core concepts, from basic syntax to object-oriented programming.

C++ was developed as an extension of C, adding modern features like classes and objects while maintaining low-level efficiency.

2. Basic Program Structure

A C++ program uses headers like iostream for I/O operations.

#include <iostream>
using namespace std;

int main() {
    cout << "Hello C++!" << endl;
    return 0;
}

3. Variables & Types

C++ is statically typed, meaning you must define the data type of each variable.

int age = 21;
double pi = 3.14;
char grade = 'A';
bool isEasy = false;

12. Object-Oriented Programming (OOP)

C++ is one of the most widely used languages for OOP, emphasizing Classes, Inheritance, and Polymorphism.

class Robot {
public:
    void greet() { cout << "Hello!" << endl; }
};

int main() {
    Robot r;
    r.greet();
}
