Arrays (cont)

Assuming an array declaration like  Type v[N ] ...
  • individual array elements are accessed via indices 0..N-1
  • total amount of space allocated to array N × sizeof(Type )
  • array name gives address of first element  (e.g. v = &v[0])
  • array indexing can be treated as  v[i] ≅ *(v+i)
Strings are just arrays of char with a '\0' terminator
  • constant strings have '\0' added automatically
  • string buffers must allow for element to hold '\0'
