#print
Write in a program which reads its input and writes it
out line numbered, with a three-digit line number (starting at one)
followed by a single space and then by the original line.
Note: the printf format specification %3d will print a three
digit number.
You might try the function fgets (part of the standard library).
	fgets(buf, size, stdin)
reads from the terminal ("stdin") up to size characters
into buf.  It returns NULL on end of file.

Compile and test your program; then type "ready".
#once #create Ref
When in the course of human events, it becomes
necessary for one people to dissolve the political bands which have
connected them with another, and to assume among the 
powers of the earth the separate and equal station to which
the laws of Nature and of Nature's God entitle them, a decent
respect to the opinions of mankind requires that they should
declare the causes which impel them to the separation.
  We hold these truths to be self evident, that all men
are created equal, that they are endowed by their creator
with certain unalienable rights, that among these are life, liberty,
and the pursuit of happiness.  That to secure these rights,
governments are instituted among men, deriving their just
powers from the consent of the governed.  That whenever
any form of government becomes destructive of these ends,
it is the right of the people to alter or to abolish it, and
to institute new government, laying its foundation on such
principles and organizing its powers in such form, as to them
shall seem most likely to effect their safety and happiness.
