Assignment #2, Problem 3


    The output of the code snippet is 1221.

Explanation: 

          p is declared as a character pointer and a is an array 
of characters. p is initialized with a+1 i.e p now points
to a[1] as 'a' contains the address of a[0]. 

Now the statment a[2] = *p assigns value at p (i.e a[1]) to a[2]

    --- char array is now 1224

p[2] = *a assigns the value a[0] to p[2] ( refers to element a[3]) 

    --- char array is now 1221 (final output)

Note:
1)    pointer subscript notation is used  (for  p[2] ).

2)    'a' is constant pointer to a[0].
