Short answer: Just get the newer version of K&R for the intro.

But in reality no.  The differences of note are:

The thing ANSI added that most people really use are the function
prototypes.   This is a really good thing.  In K&R (original), just
convert:

  foo( a, b )
  int a;
  int b;
  { ... }

to 

  void foo( int a, int b )
  { ... }

(you may have to return ints instead -- check for returns).

You will have to declare "void foo( int a, int b );" before the
function foo is referenced.  This is most often done in "#include"
files. 

ANSI also added structure copying and passing structs as args, but big
deal.  Most people still do memcpy( &a, &d, sizeof( a ) ); instead of
a=b; anyway.  Passing and returning structs is generally frowned upon
because it impacts performance.

ANSI also added some really horrid features like "tri-graphs".  Best
to avoid these.
