Change to the directory where the `hello.cpp` file is located. 3. Run the following command: ```bash g++ hello.cpp -o hello ``` This will compile the `hello.cpp` file and create an executable file called `hello`. To run the executable, use the following command: ```bash ./hello ``` The program should then print "Hello World!" to the console. ```
