typo in ddd manual

[Chris Walker]

In the ddd manual, in chapter 1, page 7 it says:

  Try this with argv to see its value (6). The local variable a is not
  yet initialized; you'll probably see 0x0 or some other invalid pointer
  value


Surely this should be argc, not argv.

It is also like this at:
