This is probably a stupid question but did you do "vim hello.c"?

Did the compile fail?  If so what error messages did you get?  Was cc not
found?  My system does not have a cc alias for gcc so I would do the
following:

gcc -g -o hello hello.c

and then run it as
./hello  # if you want to be specific about running hello from cwd
or
hello     # if you trust your path
