The "-o" option gives the name to the executable that is generated. If you 
omit it, the executable will get the default name, "a.out". To execute it, 
type

./a.out

Note the dot-slash notation before the filename --- it forces bash to execute 
the a.out command residing in the current directory. Otherwise bash will look 
for a.out in your default $PATH and typically won't be able to find any a.out 
executable.

HTH, :-)
