After entering the vim editor ,press letter “i” indicates insert mode,

Write down the following code:

After writing press “Esc” to exit insert mode, enter: wq (save and exit), enter gcc test.c (press the Tab key to incomplete filename);

The desktop gcc compiler to generate a a.out file, execute a.out,

ubuntu@ubuntu:~/Desktop$ sudo ./a.out
