Subject: problem of basic semantics and bindings
i have a problem, pls. can u provide me with the answers of these things.. thank you very much...
a. Assume the language Pascal, C, or Modula-2. Give as precise bindings times as you can for the following attributes, and give reasons for your answers:
1. the number of significant digits of a real number.
2. the meaning of char.
3. the size of array variable.
4. the size of an array parameter.
5. the location of a local variable.
6. the value of a constant.
7. the location of a function.
b. Discuss the meaning of the following statement, early binding promotes security and efficiency, while late binding promotes flexibility and expressivenes..
c. Compare the advantages and disadvantages of Pascal's declaration before use rule with Modula-2's rule that extends the scope of a declaration to the entire block, regardless of its position in the block.
d. Describe the bindings performed by a Pascal Forward declaration. why is such a declaration necessary?
e. Describe the bindings performed by a C extern declaration. Why is such a declaration necessary?

Log:
This is really mostly a test commit. This helps hugs along w/ some of
the more `interesting' fundep examples, but a final solution it is not.
When checking entailment of a derived instance decl, you check entailment
of each predicate in the context. Each of these checks may give rise to more
opportunities for `improvement'. This patch adds an improvement step
in between entailment checks.

Adding some more snowball output fixes.
This fixes the bug reported by levent (too many parens)
