It shows that source program takes         51 bytes,
              compiled object program -  1468 bytes.
This is not mauch.
Probably, the executable  hello  is 1000 times larger than object
one because some piece of  library  
(including binary code for outputting a string) 
is linked to it.  
In small user programs the library code is usually the larger 
In large user programs, it will be the smaller part.
