hello world c++

To write a "Hello, World!" program in C++, follow these steps:

  1. Include the necessary header file: At the beginning of your code, include the necessary header file using the #include directive. In this case, you need to include the iostream header file to use the input and output stream functionalities.

  2. Use the main function: In C++, the program execution starts from the main function. Declare the main function using the following syntax: int main() { }.

  3. Output the text: Inside the main function, use the std::cout object to output the desired text. In this case, you want to output "Hello, World!" to the console, so you can use the following statement: std::cout << "Hello, World!";. The << operator is used to insert the text into the output stream.

  4. Return from the main function: At the end of the main function, add a return statement to indicate a successful program termination. In this case, you can use return 0; to indicate that the program executed successfully.

Here is the complete code for the "Hello, World!" program in C++:

#include <iostream>

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