COP 5555 Programming Language Principles Homework 8 Assigned: July 20, 2011 Deadline: 11:59pm August 3, 2011 NOTE: This homework is worth 200 points (so it’s worth 2% of your whole grade) *Note: Please submit your solution to the e-learning system by the deadline. No late submission is allowed. 1. Problem 1 (30 Points) In the PowerPoint of Lecture 27, slide 21, at the end of the definition of the Pascal "for" loop, why do we have "(Replace m I \bottom, i, o)"? 2. Problem 2 (30 Points) In the same Powerpoint lecture, slide 23, at the end of the definition of the Pascal "case" statement, why do we have "o (\lambda(v,s).s)"? 3. Problem 3 (40 Points) Add a 'do' statement (as in the C language) to the denotational semantics specification of Tiny.

Unformatted text preview: 4. Problem 4 (30 Points) Consider the denotational semantics specification of Tiny. Suppose we were to make a single change to the specification of the '+' operator (slide 20 lecture ppt 26). Consider changing the LAST occurrence of s2 to s1, on the next-to-last line. Explain in plain English how the semantics of the Tiny language change due to this change in the specification. Illustrate your argument by constructing a sample Tiny program that illustrates the different semantics. 5. Problem 5 (30 Points) Why is type checking difficult in the denotational description of Tiny? 6. Problem 6 (40 Points) Write the denotational description of the 'case' statement in C for Tiny....
