                     12: for is  a C keyword that  introduces a loop.  It  takes three ar-
                     13: guments, which  are separated by  semicolons `;'.  initialization
                     14: is executed  before the loop begins.   endcondition describes the
                     15: condition that  ends the loop.  modification  is a statement that
                     16: modifies  variable to  control the  number  of iterations  of the
                     17: loop.  For example,

                     20:         for (i=0; i<10; i++)

                     22: 
                     23: first sets the variable i to zero; then it declares that the loop
                     24: will continue  as long as  i remains less than  ten; and finally,
                     25: increments i by one after  every iteration of the loop.  This en-
                     26: sures that  the loop  will iterate  exactly ten times  (from i==0
                     27: through i==9).  The statement

                     34: return  statement.  Also,  either or  both of  initialization and
                     35: modification  may   consist  of  multiple   statements  that  are
                     36: separated by commas.  For example,
                     37: 
                     38: 
                     39:         for (i=0, j=0; i<10; i++, j++)

                     41: 
                     42: initializes both i and j, and increments both with each iteration
