#include <iostream>
using namespace std;

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


Let's write a program to add two numbers in C++.

#include <iostream>

using namespace std;

int main() {
   int firstNumber, secondNumber, sum;

   cout << "Enter two integers: ";

   // Store two integers entered by user
   cin >> firstNumber >> secondNumber;

   // Sum of two numbers in stored in variable sum
   sum = firstNumber + secondNumber;

   // Display sum
   cout << firstNumber << " + " <<  secondNumber << " = " << sum;

   return 0;


Enter two integers: 4 5
4 + 5 = 9


In the above example, we have written a C++ program that takes two integers as input from the user, adds them, and displays the result. The cin statement takes in the user input and stores it in the variables firstNumber and secondNumber. The sum = firstNumber + secondNumber statement calculates the sum and saves it in the sum variable. Lastly, the cout statement prints the result to the console.


C++ is a popular programming language used for developing system software, application software, device drivers, and embedded software. It is also used for competitive programming, game development, and scientific research.

Important Points

  • C++ supports multiple inheritance and operator overloading.
  • C++ has a rich standard library that includes data structures, algorithms, and other useful tools.
  • C++ is a compiled language, which means that the code needs to be compiled before it can be executed.


In this tutorial, we have covered the basics of C++ programming, including syntax, examples, output, and important points. C++ is a powerful and flexible programming language that can be used for a wide range of applications. If you're interested in learning more, be sure to check out some of our other C++ tutorials.
