Hello World Program in C++

The "Hello, World!" program is one of the simplest programs to write in any programming language. It serves as an introduction to the syntax and basic functionality of a programming language. In C++, this program helps you understand how to output text to the console and how the basic structure of a C++ program works.

In this exercise, we will write a program that outputs the text "Hello, World!" to the console. This program demonstrates how to use the `iostream` library, which allows you to handle input and output in C++.

Key Concepts:
- Outputting text to the console using `cout`
- Basic structure of a C++ program
- Using the `iostream` library for input/output operations

Introduction to C++

Objective

1. Include the necessary header file `iostream` to use the `cout` object.
2. Write the `main()` function, which is the entry point of every C++ program.
3. Use the `cout` object to print "Hello, World!" to the console.
4. Ensure that the program compiles and runs without errors, displaying the correct output.

Write a program that prints "Hello, World!"

Example C++ Exercise

 Copy C++ Code 
#include <iostream> // Include the iostream library to handle input and output

using namespace std; // Use the standard namespace for convenience

// Main function - the entry point of the program
int main() {
    // Output "Hello, World!" to the console
    cout << "Hello, World!" << endl; // cout is used to print to the console and endl adds a new line
    return 0; // Return 0 to indicate that the program ran successfully
}

 Output

Hello, World!
