MCS-287 Chapter 6 Homework (Spring 2000)

Exercise "6.1.x": Using diagrams as in Figure 6.1.6, page 185, trace the program in Figure 6.2.3, page 193, using call-by-value with indirect arrays and with direct arrays. What sequence of four values is printed in each case?
Exercise 6.2.2. In doing this exercise, use the following corrected version of Figure 6.2.2(b) as your model, not the original, and for each case specify what sequence of four values (not one value) is printed.
Exercise "6.3.x": What value would the following expression compute using call-by-reference? What value using call-by-value-result? Explain, using diagrams to help.
```
let y = 3 in
  let p = proc(x) begin
            y := 5;
            x := +(x, 1)
          end
    in begin
      p(y);
      y
    end
```
Exercise 6.5.5. Include both what is explicitly printed by write and what is implicitly printed by the read-eval-print loop (the overall expression's value).
