Basic Structure of a C++ Program

#include <iostream> using namespace std; int main() { cout << "Hello World"; return 0; }

This program displays "Hello World" on the screen and is often the first C++ program beginners learn.

Object-Oriented Programming in C++

One important reason what is C++ used for is commonly searched online is because C++ supports object-oriented programming.

Object-oriented programming helps developers organize code using classes and objects.

Classes and Objects
Inheritance
Polymorphism
Encapsulation
Abstraction

10 Examples of C++ Programs

1. Hello World Program

#include <iostream> using namespace std; int main() { cout << "Hello World"; return 0; }

2. Addition Program

#include <iostream> using namespace std; int main() { int a = 10, b = 20; cout << a + b; return 0; }

3. Even or Odd Number

#include <iostream> using namespace std; int main() { int num = 4; if(num % 2 == 0) cout << "Even"; else cout << "Odd"; return 0; }

4. Factorial Program

#include <iostream> using namespace std; int main() { int fact = 1; for(int i = 1; i <= 5; i++) { fact *= i; } cout << fact; return 0; }

5. Fibonacci Series

#include <iostream> using namespace std; int main() { int a = 0, b = 1, c; for(int i = 1; i <= 5; i++) { c = a + b; cout << c << " "; a = b; b = c; } return 0; }

Difference Between C and C++

C is procedural programming language
C++ supports object-oriented programming
C++ supports classes and objects
C language is simpler
C++ provides advanced programming features
