c++ hello world linux

To create a "Hello World" program in C++ on Linux, follow these steps:

Step 1: Open a text editor of your choice. You can use editors like Vim, Emacs, or even a simple text editor such as Nano.

Step 2: Start a new file and save it with a ".cpp" extension. For example, you can save it as "hello_world.cpp".

Step 3: Begin writing your C++ code. In the file, type the following code:

#include <iostream>

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

Step 4: Save the file.

Step 5: Open a terminal and navigate to the directory where you saved the "hello_world.cpp" file.

Step 6: Compile the C++ code using the following command:

g++ hello_world.cpp -o hello_world

Step 7: After successful compilation, you will have an executable file named "hello_world" in your current directory.

Step 8: Run the program by executing the following command:

./hello_world

Step 9: The program will run and display "Hello World!" as the output on the terminal.

That's it! You have successfully created and executed a "Hello World" program in C++ on Linux.
