Deep Practice of Arrays

/* Declare two char arrays A and B and input the values in it . Declare another
   Array C as int array and fill it in such way that it contains 1 for the index
   where values of "A" & "B" are same and 2 otherwise . Output on the screen the
   values of all three arrays */
