Log in to a CAEN machine in Linux 2. Press the "windows" key to open the application launcher and then type "gedit" 3. Now copy-paste the following block of code into the window: ```c #include <stdio.h> int main() { printf("Hello World\n"); return 0; } ``` 4. Type "Ctrl-s" or click the "save" icon, save the file as "myprogram.c" in your home directory. 5. Press the "windows" key again and type "terminal" 6. In the window that appears, type "gcc myprogram.c -o myprogram" 7. Now type "./myprogram" ] .right-column[ 1. Open your favorite text editor and write a basic "Hello World" program 2.
