RELATIONSHIP BETWEEN POINTERS AND ARRAYS

• Arrays and pointers closely related

         –Array name like a constant pointer
         –Pointers can do array subscripting operations

• Declare an array b[5] and a pointer bPtr

          bPtr = b; 
          Array name actually a address of first element
                                         OR
          bPtr = &b[0] 
         Explicitly assign bPtr to address of first element.

• Element b[n] 

        –can be accessed by *( bPtr + n )
        –n – offset (pointer/offset notation)
        –Array itself can use pointer arithmetic.
b[3] same as *(b + 3)
        –Pointers can be subscripted (pointer/subscript notation).
           bPtr[3] same as b[3].
