A block structured language allows a name to be declared

  • A.only at the outermost level of the program text
  • B.in any block at all, with visibility extending to the whole program
  • C.in any block, with visibility limited to that block and those inside
  • D.only once in the whole program regardless of the block

Answer: C

Declarations are local to their block and to any blocks nested within it. This is what makes a chained or stacked table the natural implementation. Flat tables can only support such a language by tagging every entry with its block.
